IPv6 and BGP

I have configured 2 BGP peers, each in a different AS one of which is advertising ::/0 to the other. Doing a show bgp ipv6 ::/0 shows the next hop as the global IPv6 address of that router. but when doing a show ipv6 route for ::/0 it shows the next hop as the link local address of the next hop router.

Is this the default nature of BGP.

Kind Regards

Kev

Re: IPv6 and BGP

It is actually normal behavior for the BGP route to resolve to the local link address of the neighbor ultimately.

Hope this helps,
