[ITNOG] graceful shutdown community examples

[Job Snijders]

Dear Italian operators,

Thanks for hosting ITNOG today!

As follow-up to my presentation I wanted to share configuration examples
on how to support the well-known BGP Community "GRACEFUL_SHUTDOWN".
We're keeping track of how to implement the functionality on various
platforms here:

    http://bgpfilterguide.nlnog.net/guides/graceful_shutdown/

If you can share examples from platforms not yet covered, please mail me
so I can add them!

Make sure you implement support for graceful shutdown on each and every
EBGP session, including peering, transit, customer links: every EBGP
session.

Kind regards,

Job
