[FROG] BGPD advertises IPv4 prefixes when only IPv6 peer is up

[Richard Klingler]

Weird behaviour of frr (o;

As soon I added "no bgp default ipv4-unicast" it added activate
statements for IPv6 peers under address-family ipv4 unicast.

Needed to remove all IPv6 activate statements there...


So if I would need to advertise an IPv4 and IPv6 prefix, frr would just
need a IPv6 eBGP peer?
