Based on the provided question and exhibit, it is important to focus on the Ethernet Segment Identifier (ESI) configurations in a multi-homed EVPN-VXLAN environment. The same ESI should be configured on the links from the host to ensure proper identification and handling of broadcast, unknown unicast, and multicast (BUM) traffic. Moreover, ensuring that the source has consistent ESI configurations on its links is critical to avoid traffic loops and ensure correct packet delivery. Therefore, verification of the ESI configuration on both the host and the source side links would be prudent steps in troubleshooting the problem.
EVPN type 4 routes - Ethernet Segment Routes are needed in multi-homing scenario and used for Designated Forwarder Election.
bd is correct
Type 2 route, MAC with IP advertisement route—Type 2 routes are per-VLAN routes, so only PEs that are part of a VNI need these routes. EVPN allows an end host’s IP and MAC addresses to be advertised within the EVPN Network Layer reachability information (NLRI). This allows for control plane learning of ESI MAC addresses. Because there are many Type 2 routes, a separate route-target auto-derived per VNI helps to confine their propagation. This route type is supported by all EVPN switches and routers. Type 5 route, IP prefix Route—An IP prefix route provides encoding for inter-subnet forwarding. In the control plane, EVPN Type 5 routes are used to advertise IP prefixes for inter-subnet connectivity across data centers. To reach a tenant using connectivity provided by the EVPN Type 5 IP prefix route, data packets are sent as Layer 2 Ethernet frames encapsulated in the VXLAN header over the IP network across the data centers.
