I???d disagree. The maintenance currently taking place affects more than just the route servers. Plenty of people are doing bi-lateral peering on MICE, and that *IS* affected by maintenance events like these.
Right - but that's for the bilateral peers to work on. Forcing the issue by adding an ACL that they may not have asked for seems kind of .. intruding.
Adding an ACL to the port ensures graceful shutdown/end of traffic, rather than an abrupt drop and hold timer fun. I???d much rather that someone running the maintenance and in control of the ultimate link up/down events be the one deciding when things are starting/ending and re-enabling traffic gracefully.
I don't know if everyone accepts that. I'm playing devils advocate only.
Clean shutdown of bird is easier, quicker, and will for sure make the multilateral peering not be further affected by bouncing repeatedly.
Yes, great for MLPA, but not for bilateral.
Bilateral users are already adding to their complication by having many more peers than just going multilateral.
Why break everyone and cause a total route server outage, when it???s not necessary at all? Yesterday???s maintenance only affected a portion of members. ACL???s on member ports would be the cleanest way to minimize outage duration for all members with the least impact to the IX as a whole.
That member would have still been affected and would not have helped reduce the noise. -- Mike Horwath, reachable via drechsau@Geeks.ORG
