[c-nsp] LDP Graceful restart

[Hashiru Aminu -X (haminu - SSAI at Cisco)]

Your answer is Yes, logically you can have graceful restart on a router
that does not have multiple RSP, but you will need to have the
neighboring router to at least have the NSF/SSO feature ....

Take a look at this link.

We have seen it work as desired between multiple 7206-VXR units (which
are, by no means, hardware/distributed routing platforms, but for all
intents and purposes, have a single control plane).

Here's some log output:

Jul 27 00:26:41.874 MYT: %LDP-5-GR: GR session 192.168.0.1:0 (inst. 13):
interrupted--recovery pending

We have a couple of Junipers (M-series) that have LDP configured for GR,
but those have been stable so I have no logs to offer :-).

Cheers,

Mark.
