Hi all,

Looking for a bit of a sanity check here. I established an AS112 Server in
my testbed. I setup a dummy interface on the AS112 server (bs) for all the
subnets with an interface name that starts with 'as112_'. I set up the bird
and bird6 configuration files identically except for the prefix 'set
allnets' and or course the IPv4 remote addresses in bird.conf and IPv6
addresses in bird6.conf. What is puzzling me is that in an ISP router I can
see the IPv4 'allnets' in both the router BGP and IP routes tables but I
cannot see the IPv6 'allnets' in the BGP and IPv6 routes tables.

regards,

Diarmuid
