Figure 60 NEXT_HOP attribute configuration
If a BGP router has two peers on a broadcast network, it does not set itself as the next hop for routes sent
to an EBGP peer by default. As shown in Figure 61, Router A and Router B establish an EBGP neighbor
r
elationship, and Router B and Router C establish an IBGP neighbor relationship. They are on the same

next hop by default. However, you can configure Router B to set it (1.1.1.2/24) as the next hop for routes
sent to Router A by using the peer next-hop-local command as needed.

peer or peer group regardless of whether the peer next-hop-local command is configured.
