But on the other hand, when you try to reach BGP across the network will it
work? When the next hop is seen as an IPv4 address, doesn't that kinda mess
things up?
I can see it, I just can't get there! ;)

Subject: RE: ipv6 for bgp
well scott,
if i was asked to peer 2 router with ipv6 bgp, would i have fulfilled that
task per my example below?
when i do a "sh bgp ipv6 nei sum" i do get a neighbor 1.1.1.1, and when i
check the running config i've got the ipv6 address added to my bgp
process.............
