z To make sure an iBGP peer can find the correct next hop, you can configure routes advertised to
the IPv6 iBGP peer/peer group to use the local router as the next hop. If BGP load balancing is
configured, the local router specifies itself as the next hop of routes sent to an IPv6 iBGP
peer/peer group regardless of whether the peer next-hop-local command is configured.
z In a “third party next hop" network, that is, the two IPv6 eBGP peers reside in a common
broadcast subnet, the router does not specify itself as the next hop for routes sent to the IPv6
eBGP peer/peer group by default, unless the peer next-hop-local command is configured.
