I spoke with Jay off-list about this, and thought there might be a clever
way of doing this with a logical-tunnel, with the MPLS-CCC tunnel ending on
a logical tunnel interface, then hooking that into a regular logical
interface with an inet address for BGP peering.
As I've not used logical-tunnels yet, I wasn't able to furnish him with
further details. Might someone else be able to offer suggestions?
