BGP EVPN sessions are Established, yet a leaf installs no remote tenant routes. Investigation shows the route-target import is missing on the routing instance. What is the right fix focus?
Select an answer to reveal the explanation.
Short Explanation
Session up but empty tenant tables usually means the RT membership badge is wrong or missing — fix import/export on the EVPN instance. Twiddling OSPF hellos or cloning RDs will not subscribe you to the right routes.
Full Explanation
An Established BGP EVPN session does not guarantee VRF import. Missing or mismatched route-target import/export prevents EVPN routes from entering the tenant instance. Remediation targets RT and routing-instance configuration aligned to the VNI/VRF design. Underlay hello tuning, collapsing RDs, or abandoning VXLAN for QinQ do not restore RT membership.
