R1 (config-router)#neighbor 2.2.2.2 update-source loopback77.Next Hop Overrides. If an NHRP route in the RIB is identical to another route (owned by another protocol) in the RIB then NHRP overrides the other protocol’s next hop entries by installing shortcut next hops in the RIB. NHRP installs shortcut paths into the routing table, not as NHRP routes but as local forwarding paths.

These commands configure a route map to leak routes from VRF1 to VRF2 using route map RM1. Inter-VRF Local Route Leaking Inter-VRF local route leaking allows the leaking of routes from one VRF (the source VRF) to another VRF (the destination VRF) on the same router. Inter-VRF routes can exist in any VRF (including the default VRF) on the. ….
