Re: BGP MDT

If you remove the neighbor from the mdt address family and it still appears in the config under the address family, it seems to be a bug. There is nothing like the "no bgp default ipv4 unicast". Like Brian said, if you completely want to remove The functionality" just delete the address-family ipv4 mdt.
