Dear members of the l3vpn distribution list,

I want to introduce a new method of implementing bidirectional RSVP-TE tunnel which can be used as tunnel for virtual router based VPN. 

http://tools.ietf.org/wg/l3vpn/draft-xu-l3vpn-rsvp-te-bidirection-01.txt

In contrast with the procedure of bidirectional TE tunnel defined in GMPLS related draft [RFC 3473], there is no additional requirement on middle-hop LSRs here. The middle-hop LSRs only need to transit the unknown binding object. In addition, the modification of RSVP-TE is small relatively and the path of two opposite tunnel can be different. 

In addition, the bidirectional RSVP-TE tunnel has many other purposes, such as interconnection of two separate routing domains through a RSVP-TE tunnel and interconnection of two separate LDP-based MPLS networks through a RSVP-TE tunnel, which is also called as LDP over TE.

Any comment from you will be expected.

Best regards!
