BGP Graceful Restart

[Graham Johnston <johnston.grahamj () gmail com>]

I do believe that I understand the intended purpose of BGP
graceful-restart. With that said, I was watching a video of a talk
given by someone respected in the industry the other day on the use of
graceful-shutdown and at the beginning of the talk there was a quick
disclaimer that his topic had nothing to do with graceful-restart
along with some text on the slide that provided me a clear indication
that he was not a fan of graceful-restart.

Largely, I suspect that his point was that if you otherwise do the
right things during maintenance that graceful-restart has the
potential of being really problematic if things go wrong, and thus he
was discouraging the use of it. Is there consensus as to whether
graceful-restart has any place in a service provider network?

Thanks,
Graham
