Hi,

 

I am writing to ask advices for the newly issued internet-draft "Explicit Notification for LDP-IGP Synchronization".

 

This document proposes a mechanism to affirm the switching time accurately by propagating a explicit notification from downstream. The proposed solution can be used in a MPLS L2VPN or L3VPN scenario, to prevent any traffic from being discarded, and avoid the important traffic from being forwarded through a non-optimal path in long time even if the optimal path is operational.

 

Any suggestion or opinion of the mechanism will be appreciated. Looking forward to your reply!

 

Details of the document is as follows:

 

> Title : Explicit Notification for LDP-IGP Synchronization
> Author(s) : E. Chen
> Filename : draft-chen-mpls-ldpigp-syn-accurate-00.txt
> Pages : 10
> Date : 2007-6-18
