Subject: Regarding l2tp-mpls extension

Regarding l2tp-mpls extension:

The draft on l2tp-mpls-extension "draft-ietf-l2tpext-mpls-00"
proposes that the l2tp peers exchange an LSPID in a new AVP
defined for carrying the LSPID.

The objective is that L2TP Data Sessions can be assigned an
MPLS Label Switched Path Id (LSPID) for an explicit route (ER).

What is the basis of mapping a session to an LSPID? I'm not
asking for the mechanism to get an LSPID - that's the job of
CRLDP, sure. I'm asking how do you decide that session-A is
to use LSPID-1 and session-B to use LSPID-2 and so on....

Is this based on user-id in the PPP session? - which then
suggests that ProxyLCP is a necessity at the LAC?

Any comments......

Thanks
Rajesh
