Hi,

     announce (IPv4|IPv6) (none|unicast|vpn)
             For the given address family, control which subsequent address
             families (at the moment, only none, which disables the
             announcement of that address family, unicast, and vpn, which
             allows the distribution of BGP MPLS VPNs, are supported) are
             announced during the capabilities negotiation.  Only routes for
             that address family and subsequent address family will be
             announced and processed.

Since I only want/need/have unicast address family, there is apparently
no need to change it.

After trying with this statement removed, it doesn't change anything :(

Sure I do. Internal routing between loopback interfaces is done through
OSPF.

I tried with disabled filters, it didn't help either.

I'll no matter what still continue to find where this issue comes from.

Cheers,
