MICE Core Switch Card Upgrade
by Richard Laager 08 Feb '24

08 Feb '24

Date & Time Wednesday, February 14 at 15:00 US/Central Description Jeremy will swap a (now unused) 10G line card for a 100G line card in the Arista core switch at 511. There is no expected impact for most participants. In the (relatively unlikely) event that a fiber cable is physically in the way and he has to unplug it to remove/install the card, he will disable BGP for that participant first and wait (unless the port is part of a LAG with sufficient excess capacity at that time of day). The Fiber Minnesota and Minnesota VoIP remote switches are connected by 3x100G LAG. Jeremy will move one port from each LAG from card 6 to the new card. Rollback Plan If there is some problem, the new 100G card can be removed. The ports in the Fiber Minnesota and Minnesota VoIP remote switches can be moved back to card 6. -- Richard

BGP ADD-PATH capability
by Richard Laager 24 Jan '24

24 Jan '24

I propose that MICE enable BGP ADD-PATH capability (RFC 7911) on the route servers (in TX mode only). This is negotiated BGP capability, so we do not need any per-participant setting for it. ADD-PATH is useful if the best path route is being filtered but another route would not be. We discussed adding this at a UG meeting years ago. There are other IXPs that have this enabled. For example, this one: https://www.bcix.de/ixp/content/0/route-servers In terms of timeline, I propose something like this: * January 9: Enable it on Route Server 1. * January 16: Enable it on Route Server 2. The actual change looks like this for the RS1-only piece, and then the conditional would be removed when we want to deploy to RS2: --- a/roles/ixpmanager/files/mice/api/v4/router/server/bird2/neighbors.foil.php +++ b/roles/ixpmanager/files/mice/api/v4/router/server/bird2/neighbors.foil.php @@ -315,6 +315,9 @@ protocol bgp pb_<?= $int['fvliid'] ?>_as<?= $int['autsys'] ?> from tb_rsclient { import filter f_import_as<?= $int['autsys'] ?>; table t_<?= $int['fvliid'] ?>_as<?= $int['autsys'] ?>; export filter f_export_as<?= $int['autsys'] ?>; +<?php if( $t->router->router_id == "206.108.255.1" ): ?> + add paths tx; +<?php endif; ?> }; <?php if( $int['bgpmd5secret'] && !$t->router->skip_md5 ): ?> password "<?= $int['bgpmd5secret'] ?>"; -- Richard

MICE Maintenance 2024-01-18 & 2024-01-19
by Richard Laager 09 Jan '24

09 Jan '24

Date & Time January 18, 00:00 - 05:00 US/Central January 19, 00:00 - 05:00 US/Central Description Our underlying fiber provider will be doing maintenance on the connection from 511 to Ridgeview. They are attempting to repair some other fiber issues. We may or may not go down. If we did go down, participants on the 511 side would see a loss of BGP to Route Server 2. -- Richard

Route servers?
by Miles McCredie 03 Jan '24

03 Jan '24

FWIW, the AS11232 sessions to route server 2 have been active for about 25 minutes. https://ixpmgr.micemn.net/lg/rs2-ipv4 and https://ixpmgr.micemn.net/lg/rs2-ipv6 <https://ixpmgr.micemn.net/lg/rs2-ipv6%20show%20that%20AS11232> show quite a few other ASNs that are not established. https://ixpmgr.micemn.net/lg/rs1-ipv4 and https://ixpmgr.micemn.net/lg/rs1-ipv6 show more not-established sessions than I would expect but fewer than rs2. I haven't looked more closely at the impact to routing yet. Any details about the work in progress?
