In the core VRF, when BGP receives a BGP-labeled VPN route from a multihop VPN peer, it attempts to resolve the BGP indirect next hop in the IP tunnel routing table. If the labeled VPN route is received from a nonmultihop peer, then the BGP indirect next hop is always resolved, because a connected route to that peer exists in the IP tunnel routing table.
Table 64 summarizes indirect next hop resolution.
