The control plane uses a MAC Mobility extended community and sequence number behavior to determine the most recent valid location for the MAC. When a PE locally learns a MAC that was previously learned through EVPN, it advertises the MAC with an incremented sequence number, allowing remote PEs to prefer the newer location. Therefore, option B is wrong because the sequence number is not decremented. Option A is also wrong because the original PE does not advertise the locally learned MAC with a maximum sequence value as a normal mobility procedure. Option D is inaccurate because PEs do not need direct MAC table synchronization; they rely on EVPN control-plane advertisements and withdrawals. The true statement is option C: the originating PE generates a withdraw message after the same locally learned MAC ages out. This withdrawal removes stale reachability from remote PEs and prevents continued forwarding toward a PE that no longer has the host locally attached.

Therefore, if a `local-as` value is configured within the BGP group used for EVPN MP-BGP route-reflector sessions, that value overrides the AS number configured directly under the BGP protocol for that group&#8217;s sessions. Option A is correct. Option B is false because the cluster ID is configured on the route reflector, not on every participating client. The cluster ID identifies the RR cluster and helps prevent route-reflection loops. Option C is false because redundant route reflectors normally operate in parallel rather than as strict primary\/backup devices; clients can peer with both for resilience. Option D is misleading because EVPN route reflectors are used to avoid a full mesh of overlay MP-BGP EVPN sessions between leaves, not to replace ordinary underlay eBGP leaf-spine routing sessions. In a clean fabric design, the underlay provides IP reachability, while the EVPN overlay uses MP-BGP sessions, often via route reflectors, to distribute tenant reachability.

The egress PE does not perform another IP-VRF lookup for that packet; it performs Layer 2 forwarding in the destination MAC-VRF. In this scenario, Host-2 sends traffic toward Host-1. After the ingress routing decision, the traffic arrives at Leaf-2 in the context of the destination MAC-VRF, mac-vrf-1. Leaf-2 then performs a MAC lookup in mac-vrf-1 and forwards the frame to Host-1. Option D is therefore correct. Option A reverses the forwarding direction and misidentifies the leaf action. Option B incorrectly sends mac-vrf-2 traffic toward the IP-VRF on Leaf-2, even though Leaf-2 is acting as the egress PE for Host-1. Option C is also incorrect because the egress forwarding action is based on the MAC table in the destination MAC-VRF, not an IP-VRF ARP lookup at that stage.

For EVPN distribution, the relevant control-plane advertisement is an EVPN route type 2 MAC\/IP advertisement containing Host-1&#8217;s MAC and the actual host IP address, 192.168.100.1. This allows remote PEs to populate their EVPN-derived forwarding and proxy ARP state with the correct endpoint binding. Option A is false because advertising the host MAC with the IP address set to 0.0.0.0 does not represent the learned MAC\/IP binding required for proxy ARP synchronization. A MAC-only RT-2 advertisement may exist in EVPN contexts, but the question specifically states that Leaf-1 has learned the MAC\/IP binding through ARP and is distributing that information. Therefore, the valid advertisement must include the real host IP address. Remote PEs use the MAC\/IP route to learn the endpoint, not an all-zero IP placeholder for this proxy ARP learning event.

The route reflector then reflects the update to Leaf-2 and Leaf-3, and those remote leaves import the route if the route target matches their MAC VRF-1 import policy. The route target controls service membership, ensuring that only PEs participating in the same EVPN instance import the MAC route.

In SR Linux EVPN services, route targets determine which MAC-VRF or IP-VRF should import a received EVPN route. This is essential for tenant separation because multiple tenants may use overlapping MAC or IP address spaces while sharing the same physical fabric and BGP control plane. The AFI\/SAFI is not an extended community; it identifies the BGP address family and subsequent address family used to carry EVPN NLRI. The EVPN route type is also not an extended community; it is part of the EVPN NLRI structure and identifies whether the route is RT-1, RT-2, RT-3, RT-4, RT-5, and so on. The VXLAN network ID may be carried or inferred through service and encapsulation-specific attributes, but it is not universally present as the required extended community in every EVPN update. The route target is the mandatory policy element that enables receiving PEs to place EVPN routes into the correct service context.

This avoids a traffic bottleneck and enables load-sharing in all-active multi-homing designs. The route type used to implement this behavior is the Ethernet Auto-Discovery per EVI route, commonly referred to as AD per EVI. This route tells remote PEs that a given PE has reachability to a specific Ethernet Segment for a specific EVPN instance. When remote PEs receive these advertisements from multiple PEs for the same ESI and EVI, they can treat those PEs as valid next-hops for traffic toward that Ethernet Segment. Ethernet Segment routes support ES discovery and DF election, while IP\/MAC routes advertise host MAC and optionally IP binding information. AD per ES routes are used for broader Ethernet Segment-level procedures, but aliasing at the service level relies on AD per EVI reachability.

Because the leaf routers or route reflectors must establish the necessary EVPN control-plane and VXLAN data-plane reachability across data centers, the WAN must provide reachability for those fabric endpoints. This design can simplify service continuity and preserve the EVPN overlay model end-to-end, but it does not provide the clean security and QoS demarcation that exists in a decoupled gateway model. A clear demarcation between a border leaf and a separate gateway\/WAN PE is specifically a property of decoupled gateway-based DCI, not gateway-less DCI.

routing relies heavily on host MAC\/IP information because the ingress PE performs routing into the destination subnet and then sends the frame across the overlay using the destination MAC-VRF\/VNI. This means PEs require enough ARP and MAC\/IP binding information to forward traffic toward remote hosts correctly. If a host has multiple IP addresses on the same interface, separate EVPN route type 2 advertisements may be needed to communicate each IP-to-MAC binding. The ingress and egress PEs participate in MAC and IP forwarding across the end-to-end service path, but the forwarding responsibilities differ by direction and stage. The false statement is option C. The statement says all MAC-VRFs connected to the L3 EVPN network must exist on each PE, but that is not the correct requirement in this question&#8217;s verified answer set. In practical EVPN designs, the exact MAC-VRF placement depends on whether the service is implemented as asymmetric, symmetric, interface-less, or interface-ful routing. Here, the course answer marks the universal MAC-VRF requirement as false.

Traffic between them can be identified using VLAN tags, allowing different data center EVPN services to be mapped to corresponding WAN VPN services. This architecture provides a clean operational boundary: the border leaf remains aligned with the data center EVPN\/VXLAN fabric, while the WAN PE handles WAN VPN transport, QoS, security policy, and service interconnection. The separation gives a strong demarcation point for troubleshooting and administrative control. Option D is false because the WAN PE does not maintain an MP-BGP EVPN peering session with the data center route reflector. In the decoupled model, the route reflector remains part of the data center EVPN control plane, while the WAN PE exchanges routing or service information with the border leaf through the local handoff model. Direct WAN PE-to-data-center-RR peering would blur the separation that defines the decoupled design and would make the WAN PE part of the data center EVPN overlay control plane, which is not the intended architecture.

This is why option D is correct. The device terminates or participates in the data center-side EVPN service and also handles the WAN-side VPN transport, including route translation or re-advertisement where needed. This approach avoids exposing every data center leaf router to the WAN and avoids requiring route reflector reachability between data centers. It also avoids building VXLAN tunnels directly between all leaf routers in separate data centers. Those characteristics belong to gateway-less DCI, where the EVPN overlay stretches more directly across the WAN and the WAN must carry the underlay or overlay reachability required by the data center leaves. Integrated gateway design is more controlled: the gateway is the interworking point, which makes it suitable when the provider or operator wants a strong service boundary and centralized DCI policy enforcement.

Interconnect\/Course Guide\/topics]:<br\/>For Layer 2 all-active EVPN multi-homing on SR Linux, the Ethernet Segment configuration is the control-plane anchor that binds the redundant access attachment to EVPN. The relevant LAG subinterfaces must be associated with the Ethernet Segment so that the PE can advertise the segment correctly and apply split-horizon and aliasing behavior. The Ethernet Segment must also be administratively enabled; otherwise, the PE will not participate properly in ES discovery and DF procedures. The multi-homing mode must be set to all-active to permit forwarding through multiple attached leaf routers and support host-side LAG operation. The false statement is option B. The Ethernet Segment Identifier has a defined structure, and the blanket statement that the 2nd through 7th octets &#8220;must not be all zeros&#8221; is not a valid requirement as stated. What matters operationally is that the ESI uniquely identifies the same multi-homed Ethernet Segment across participating PEs and is consistently configured where required. The ESI must be non-zero as a meaningful segment identifier, but the specific octet restriction in the option is not the SR Linux all-active configuration rule.

The participating leaf routers must configure the LAG and associate it with the Ethernet Segment so EVPN can advertise the common ESI and apply aliasing, split-horizon, and DF procedures. If VLAN tagging is used for service separation, tagging must be configured on the LAG interface so that the correct subinterfaces can bind into the MAC-VRF and Ethernet Segment. Option C is false because it states that the LACP system-id-mac must uniquely identify each leaf router. In an all-active EVPN multihomed LAG, the opposite principle applies: from the host&#8217;s LACP perspective, the multihomed leaf pair must appear as a single logical LACP system. That generally requires a shared LACP system ID or coordinated system MAC behavior across the participating PEs. If each leaf presented a unique LACP system identity, the host would treat them as separate LAG partners and the all-active bundle would not form correctly.

The egress PE performs Layer 2 MAC forwarding only toward the destination host. This is why options A and B correctly describe asymmetric data-plane behavior. Asymmetric routing relies heavily on EVPN route type 2 MAC\/IP Advertisement routes because the ingress PE must know the destination host&#8217;s MAC\/IP binding and the destination bridge domain information. EVPN route type 5, which advertises IP prefixes, is a symmetric L3 EVPN mechanism and is not mandatory for asymmetric routing. Therefore, option C is false. Option D is treated as correct in this asymmetric-routing model because each PE participating in inter-subnet forwarding needs the destination MAC-VRF context to encapsulate traffic toward the correct L2 VNI. This requirement is one reason asymmetric routing scales less efficiently than symmetric routing: MAC-VRF presence and host reachability information must be broadly available. Symmetric routing improves scale by using an IP-VRF routed VXLAN interface and RT-5 prefix routes instead.

In single-active L3 multi-homing, DF election determines which attached leaf is active for the Ethernet Segment, and only that leaf advertises or forwards for the attached customer route as required by the redundancy model. In all-active L3 multi-homing, multiple leaf routers can be valid next-hops for the same learned third-party prefix, and remote PEs may load-balance toward them based on the Ethernet Segment association. Learned external prefixes are carried as EVPN route type 5 IP Prefix routes, which is the correct route type for L3 reachability. The Ethernet Segment is associated with the next-hop for those prefixes so that remote PEs understand the multi-homed nature of the path. Option B is false because BUM forwarding is a Layer 2 EVPN concern. In an all-active L3 multi-homing scenario, DF election is not used to identify a BUM-forwarding leaf for host traffic in the same way it is used in Layer 2 multi-homing services.

For Layer 3 VPN connectivity on a Nokia 7750 SR integrated gateway, the base BGP instance must support the relevant VPN address families, such as VPN-IPv4 and EVPN, because the gateway participates in control-plane exchange between the data center and WAN sides. The VPRN must also be associated with the WAN transport, normally through MPLS tunnel binding, and the VRF target must match the corresponding VPRN on the remote gateway so that VPN routes are imported and exported correctly. A routed VXLAN interface, however, is an SR Linux IP-VRF\/VXLAN construct used for symmetric L3 EVPN forwarding inside a VXLAN-based data center fabric. In this question, dcgw10 is acting as the integrated WAN gateway for L3VPN connectivity, so a routed VXLAN interface is not the required configuration item on the VPRN instance.

The EVPN overlay, however, is a separate MP-BGP control plane used to distribute EVPN NLRI. The overlay route-reflector session does not have to reuse the leaf&#8217;s underlay autonomous system number. In practice, an overlay BGP group may use a distinct local AS or configuration model separate from the underlay AS design. Therefore, option B is false. The route reflector&#8217;s cluster ID is configured on the route reflector itself to prevent reflection loops and identify the RR cluster. Redundant route reflectors can be deployed for resiliency, and clients may receive duplicate paths or duplicate updates from multiple RRs; the BGP decision process and route reflection rules handle this. The key design distinction is that underlay eBGP provides IP reachability between loopbacks, while overlay MP-BGP EVPN carries tenant service reachability. Mixing these roles leads to incorrect AS planning.

This allows tenant bridge domains to span a routed IP fabric without requiring the underlay itself to behave like one large Layer 2 network. VXLAN uses a 24-bit VXLAN Network Identifier, which supports approximately 16 million logical overlays, far exceeding the scale of traditional 12-bit VLAN IDs. Because the VXLAN underlay is IP-routed, traffic can benefit from ECMP across equal-cost paths, improving fabric utilization and resiliency. The false statement is B. VXLAN was not originally developed specifically to support EVPN. VXLAN began as a data-plane overlay encapsulation technology, while EVPN later became the preferred control plane for distributing MAC, MAC\/IP, multicast, and prefix reachability in VXLAN-based fabrics. In modern data center design, EVPN and VXLAN are commonly paired: VXLAN supplies the encapsulation and VNI-based segmentation, while EVPN supplies scalable control-plane learning and signaling.

Leaf1 and Leaf2 participate in DF election, and the elected DF becomes the active forwarding PE for that service attachment. Because this is not all-active multi-homing, the non-DF must not forward traffic to the host for the protected service. This prevents duplicate frames, incorrect MAC learning, and loops on the access side. The DF accepts traffic from the host and forwards BUM traffic received from remote PEs toward the host-facing segment. Option D is false because it claims that the non-DF can forward unicast traffic from remote PEs to the host. In single-active operation, remote peers must direct traffic to the active PE, and the standby PE remains ready to take over only after DF state changes. This is the operational distinction from all-active multi-homing, where more than one PE may be used for forwarding depending on the traffic type and aliasing behavior.

A PE sends an AD per EVI route for each MAC-VRF associated with the Ethernet Segment. These routes allow remote PEs to understand that the advertising PE has reachability to a given EVI through the shared ES. They are also used for aliasing and fast convergence, because a remote PE can treat multiple attached PEs as valid paths for traffic toward the same multihomed segment. In VXLAN EVPN, the update can include data-plane information such as the VNI, and it carries route-target information so the route is imported into the correct MAC-VRF. Option B is false because the multi-homing type or redundancy mode is not carried in the AD per EVI update as stated. Redundancy behavior is associated with Ethernet Segment-level signaling and configuration, especially ES discovery and related route attributes, not with AD per EVI as the mechanism that declares the multi-homing type.
