Hi all,

Does anybody use MPLS interface as a layer 3 logical interface, or 
subinterface (part of a physical interface), like ATM PVC or Frame Relay 
DLCI, with its own entry in ifTable (mpls(166) ifType from IANAifType-MIB) 
and IP address associated with it? Of course, it makes sense for static MPLS 
configuration of bidirectional flows.

I think it can be useful for multiplexing of small traffic flows onto big 
capacity MPLS trunk. Another possible application is eliminating of 
complexity of forwarding adjacencies in routing protocols (LSP hierarchy 
draft), where simple static MPLS path can be used as actual, not virtual 
interface. In latter case MPLS interface can be even unnumbered, without IP 
address.

Thanks,
Igor
