Two PTX100002-36QDD routers running JunOS Evolved 23.4R2-S3-EVO are configured with a link between their et-0/0/30:0 interfaces.

The routers are set up for EVPN Type 5 peering within the routing-instance called EVPN-L3-VRF_TEST, with lo0.2 interfaces included in the same routing instance.

The peering is established, and prefixes for the remote router's lo0.2 IP are visible. However, there is an issue where pinging from one side to the other fails.

Peering Status: The EVPN Type 5 peering is up, and remote prefixes are visible.

Ping Failure: Despite the peering being up, pinging between the routers fails, indicating a problem with forwarding traffic.

To resolve this, add the following configuration:

set forwarding-options tunnel-termination

This configuration is mandatory on PTX Series Routers in EVPN-VXLAN deployments since JunOS Evolved release 23.1R1.

After applying this configuration, commit the changes and verify by pinging again within the routing instance.

Successful ping responses should confirm the resolution of the issue.
