BGPD advertises IPv4 prefixes when only IPv6 peer is up
Good afternoon (o; New to FRR running two VM Debian 12 instances with FRR 10.4.0 for testing BGP setups. On each side I have v4 and v6 peers configured, but v4 is in admin shut state. But I see IPv4 prefix being advertised over the v6 BGP session. Is that a normal behaviour in FRR? thanks in advance richard

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?
