Figure 54 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 55, 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 r o a d c a s t n e t w o r k 1.1.1.0 / 24 . W h e n R o 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.
