Not quite. An address family simply says "what are we going to talk about?"
Don't confuse BGP with IP routing protocols. BGP is an application that
discusses IP routes. By default it talks about IPv4 routes 'cause that's
what it was created for. However, it also discusses other things like
VPNv4, Multicast and IPv6. The application is still the application.
So in your example there, you are peering two IPv4 devices with an IPv4 TCP
application to talk about IPv6 routes. You may now know where these routes
are but have nowhere to use them!
It's kinda like you and I discussing some entertaining words in Japanese.
While it may be very nice that we now know a few choice words, it's not like
either of us has any place to actually use that knowledge (at least in my
case!).
HTH,
Scott

What's the physical link over which BGP is trying to peer?
It does make a difference.

Subject: ipv6 for bgp
just wondering if my observations were correct..........
if you have a peer that runs both ipv4 and ipv6 and you do the following:
router bgp 100
neighbor 1.1.1.1 remote 100
address-family ipv6
neighbor 1.1.1.1 activate
the result is that both ipv4 and ipv6 adjacencies come up.
i checked the running config after and found the ipv6 address mapping in the
config, but when i do a "show bgp ipv6 neighbor" it does not show the ipv6
address of the remote host, hence my question............
