Hi!
Is it normal for a BGP ipv6 neighbor to appear under ipv4 address-family as "no activate"?
For example:
(I removed many commands for brevity, but that's a real config)
router bgp AAAAAA
neighbor X:X:X::X remote-as AAAAAA
neighbor X:X:X::X description BBBBBBB
neighbor X:X:X::X password CCCCCC
neighbor X:X:X::X update-source Loopback0
[snip]
address-family ipv4
no neighbor X:X:X::X activate <---appeared by itself
[snip]
address-family ipv6
neighbor X:X:X::X activate
Maybe it is OK, just haven't ran across this before.
Thanks!

Yes, this is normal behavior. The previous behavior in IOS was to activate address-family ipv4 for all neighbors, including the ipv6 neighbor. This behavior was changed a couple of years back to configure an explicit "no neighbor activate" for ipv6 neighbor", therefore if you ever need to activate address-family ipv4 on an ipv6 neighbor (not recommended), you should explicitly configure it.
