Title : Setup of Pseudowires over bi-directional LSP
Author(s) : W. Cao
Filename : draft-cao-pwe3-setup-over-bidir-lsp-00.txt
Pages : 12

In MPLS and MPLS-TE environments pseudo wires use two unidirectional
LSPs as PSN tunnels, the two PEs select LSP tunnels independently. In
contrast the MPLS-TP environment supports both bidirectional and
unidirectional LSPs and PWE may, therefore, use bidirectional LSPs as
PSN tunnels.
In order to use MPLS-TP bidirectional LSPs as a PSN tunnels for
pseudo wires some modification of the pseudowire signaling procedures
is required. This draft specifies an extension to LDP that ensures
pseudo-wires are correctly constructed over bi-directional LSPs.
