Re: [mpls] New Liaison Statement, "LS on work on MPLS-TP protection"

["Andrew G. Malis" <[e-mail]>]

Scott,

PALS currently has two drafts in progress that are relevant to MPLS-TP PW
linear protection:

https://datatracker.ietf.org/doc/draft-ietf-pals-mpls-tp-dual-homing-coordination/
https://datatracker.ietf.org/doc/draft-ietf-pals-mpls-tp-dual-homing-protection/

These drafts provide a fast protection mechanism for MPLS-TP PWs to protect
dual-homed CEs against failures of their attachment circuits or PE routers.
The drafts are ongoing work and were very recently updated. We hope to
forward the drafts to the IESG perhaps by the Berlin IETF meeting, and
would very much appreciate SG15’s review and comments.

Cheers,
Andy
