3. Run:
ipv6-family [ unicast ]
The BGP IPv6 unicast address family view is displayed.
4. Run:
peer ipv6-address next-hop-local
The local address is configured as the next hop when routes are advertised.
In some networking environments, to ensure that the IBGP neighbors find the correct
next hop, configure the next hop address as its own address when routes are advertised
to the IBGP peers.
NOTE
If BGP load balancing is configured, the local switch changes the next hop address to its own
address when advertising routes to the IBGP peer groups, regardless of whether the peer next-
hop-local command is used.
