Edge node failure protection for LDP-signaled pseudowires

This feature provides a fast protection mechanism against egress PE router failure when transport LSPs are RSVP-TE LSPs. This is achieved by using multihomed CEs, upstream assigned labels, context-specific label switching (egress-protection and context-identifier statements), and by extending RSVP facility backup fast reroute (FRR) to enable node protection at the penultimate hop router of the LSP. With node protection capability, the penultimate hop router can perform local repair upon an egress PE failure and redirect pseudowire traffic very quickly to a protector PE through a bypass LSP. You must configure a Layer 2 circuit and transport LSP to enable this feature. Use the show rsvp session and show mpls lsp commands to view bypass LSP and backup LSP information on the penultimate hop router and a protector PE router.
