Working through the basics of routing protocols in IPv6 and noticed  
something that seemed strange to me...  When creating BGP peerings  
between 2 routers (EBGP or IBGP, not important) I started out by  
configuring it like this...
For brevity...  Assume routes are being passed in the BGP table and  
IPv6 address/unicast-routing is configured.
R1:
E0/0: 1.1.1.1
router bgp 1
neighbor 2.2.2.2 remote 1
address-family ipv6
neighbor 2.2.2.2 remote 1
neighbor 2.2.2.2 activate
R2:
E0/0:  2.2.2.2
router bgp 1
neighbor 1.1.1.1 remote 1
address-family ipv6
neighbor 1.1.1.1 remote 1
neighbor 1.1.1.1 activate
What I'm having trouble seeing is BGP routes being passed even though  
these neighbor relationships come up under "sh bgp ipv6 unicast  
summary".  When I change the address-family ipv6 commands to peer  
with IPv6 addresses instead of IPv4 I am seeing these routes appear  
in the IPv6 BGP table.  I can't find a really good explanation of  
this.  Is there some basic rule for running IPv6 BGP alongside IPv4  
that I'm missing?
