Hi Brian,
Thank you for your reply.
So good configururation behaviour should be that for instance with
intra-as-mpls vpn .. you only send-labels for the vpnv4 prefixes and not for
the ebgp prefixes between the as-es... But why can't I set the send-label
command to the vpnv4 addressfamily neighbors but only to ipv4 unicast address
family.. I'm missing something, hopefully you can help me.
Regards
