[FROG] 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
