Hi Wim,

Thanks for the comments.

[yshen] Yes, it will. After the recovery of AC or egress PE, the PLR should re-install the forwarding entry of the primary path, and switch traffic from the bypass LSP back to the primary path. Of course, local reversion may be managed by policy on the PLR.

[yshen] Yes, the new defined "protection FEC element" can support FEC 129. MS-PW is a good suggestion.

[yshen] Good suggestions.
