Configuring the NEXT_HOP attribute
You can use the
peer next-hop-local
command to specify the local router as the next hop of routes
sent to an IPv6 multicast IBGP peer or a peer group. If load balancing is configured, the router
specifies itself as the next hop of routes sent to the IPv6 multicast IBGP peer or the peer group
regardless of whether the
peer next-hop-local
command is configured.
In the environment where the local router has two IPv6 multicast EBGP peers in a broadcast network,
the router does not specify itself as the next hop of routes sent to the EBGP peers by default.
To specify the router as the next hop of routes sent to a peer or a peer group:
