Re: Regarding Reversion

[Amit 70405 <AmitG@huawei.com>]

Hi Dimitri,
   Thanks a lot for replying.

   But depending on GR may lead to below problems:
   - For all the LSP's, on restart(or failure) a notification MAY be sent to the upstream of the LSP about the failure. And if the upstream(Ingress) decides to delete the LSP, then upstream MAY only delete it till the restarted node. Downstream to the Retarted node the LSP will continue to exist as result of GR process till the GR completes.
   - And if a restarting node or the neighbor node doesnt support GR than it will not be possible to retain the LSP.

   Yes but I agree with you that GR can be used for Reversion.
   Thanks a lot again.

Regards,
Amit.
