Abstract:
Techniques disclosed herein provide a method and systems for installing routes by a route reflect (RR) device when the tunnel RIB of the RR device does not include any tunnel labels definitions. The unicast routing information base (RIB) of route reflector (RR) device is configured to include a next hop associated with a first network device. When the RR device receives a route from the first network device that comprises a tunnel label for reaching the second network device, the RR device resolves the next hop of the received route using the unicast RIB of the RR device. In response to the resolving, the RR device forwards the route to a third network device (e.g., identified by an export route target of the RR device).
