Figure 57 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 58, R
outer A and Router B establish an EBGP neighbor
relationship, and Router B and Router C establish an IBGP neighbor relationship. They are on the same
b ro a d c a s t n e t w o r k 1.1.1. 0 / 24 . W h e n Ro u t e r B s e n d s E B G P routes to Router A, it does not set itself as the
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.

IMPORTANT:
If you have configured BGP load balancing, the router sets itself as the next hop for routes sent to an IBGP
peer or peer group regardless of whether the peer next-hop-local command is configured.
