Re: Regarding Reversion

amit, upon data plane failure there is no such behaviour as you mention - local data plane failure detection does not imply state deletion and common PathErr/ResvErr do not trigger any state deletion nor does a Notify; in particular, in the present context where one do assume control plane availability even in case of data plane failure - note: details of it available in other documents - states can be kept refreshed

Subject: Re: Regarding Reversion

Hi,
Thanks for replying.

According to the statement I mentioned from the draft, I understand that, if there is a failure the old working LSP should not be deleted.

But not only for RSVP, for any MPLS Signaling protocol, it is mandatory that when a failure happens, you should start tearing down the LSP.

Take for instance if a OutInterface(on which LSP is setup) goes down.
Protocol will lead to LSP deletion.

Plz correct me if I am wrong.
Regards,
Amit.
