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 MBGP IBGP peer or a peer group. If load balancing is configured, the router specifies itself as the
next hop of route advertisements to the 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 multicast EBGP peers in a broadcast network, the
router does not specify itself as the next hop of routing information sent to the EBGP peers unless the peer
next-hop-local command is configured.
To specify the router as the next hop of routes sent to a peer or a peer group:
