Dear members of the mpls distribution list: I would like to introduce some ideas about Bidirectional RSVP-TE tunnel, any comments from you is welcomed. Through the binding of two unidirectional RSVP-TE tunnels established between a pair of LSRs destined to each other, a bidirectional RSVP-TE tunnel is formed. Like GRE/IPsec tunnel. The bidirectional RSVP-TE tunnel can be used to establish L3VPN with virtual router. In contrast to BGP/MPLS VPN defined in [RFC2547bis], multicast is easier to be implemented and multicast traffics can travel in RSVP-TE tunnel with such L3VPN. This L3VPN fully inherits the property of RSVP-TE, such as TE, QoS and fast convergence features. 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 implementing LDP over TE. The decision factors of RSVP-TE tunnel binding include tunnel source address, tunnel destination address and binding key. The reason for making binding key as one of the decision factors is that a LSR can setup different RSVP-TE tunnels with the same pair of tunnel source address and tunnel destination address, but these tunnel interfaces must be configured with different binding keys. Any comment is welcomed! Best regards!
