Hi All,

I need clarification on the LDP MT behavior.

                LDP extension for Multi-Topology explains following :

1.       New Address Families: MT IP

2.       LDP FEC Elements with MT IP AF

3.       LDP MT Capability Advertisement

As per LDP Specification RFC 5036, Address Family filed is carried in FEC TLV and Address List TLV.

Nothing about Address List TLV is mentioned in LDP Multi-Topology Extensions RFC 7307,
Can we use  "New Address Families: MT IP" in Address List TLV or not ? (when a interface is bound to Non-default MT)
I feel this can be explained more specifically similar to FEC TLV in LDP Multi-Topology Extensions RFC 7307.

Appreciate if authors or community members can help to clarify.

Thanks & Regards
Anil S N
