BGP MVPN routes are basically 7 types of routing information distributed in BGP as prefixes.  Some of these routes are effectively fixed length but that's a minor detail.  Please refer to section 4 for the different route formats to avoid significant copy and paste.

My proposal is that 7 code points are allocated for MVPN routes for InetAddressType for these 7 types of information.  Textual conventions would be defined to cover each of the appropriate types.

One small annoyance is that the DISPLAY-HINT syntax isn't quite flexible enough to cover the variable-length types in a fully pleasing format.  There's not much we can do about that.

If this proposal seems to have merit and would be likely to get traction, we'll submit some text for the MIB.
