BIRD is complaining that various peers are sending BFD packets with an unknown session id. Anyone have thoughts on this? The logs look like this: 2024-02-07 23:44:14 <RMT> bfd1: Bad packet from YOUR_IP - unknown session id (SOME_INTEGER) Those marked with an asterisk were doing this yesterday, so prior to the reboot of rs2. rs1: Inteliquent (Neutral Tandem) 206.108.255.137 * rs2: les.net 2001:504:27::4813:0:1 Savage Communications 206.108.255.17 * 2001:504:27::5adc:0:1 * Stellar Association 206.108.255.53 2001:504:27::8e16:0:1 * Hoyos Consulting 2001:504:27::d15d:0:1 Eastern Iowa Data Group 206.108.255.168 * 2001:504:27::f7a2:0:1 * Omnitel Communications 206.108.255.148 Here is for the entire month of January: rlaager@rs1:~$ rg "^2024-01-.*Bad packet from" /var/log/bird/rs1-ipv*.1 | awk '{print $8}' | sort | uniq -c 9 2001:504:27::3823:0:2 2 2001:504:27::8252:0:1 1183836 2001:504:27::b7f8:0:1 4 2001:504:27::d15d:0:1 1183834 206.108.255.101 7498 206.108.255.119 380 206.108.255.121 1463099 206.108.255.137 3 206.108.255.176 3 206.108.255.185 root@rs2:~# rg "^2024-01-.*Bad packet from" /var/log/bird/rs2-ipv*.1 | awk '{print $8}' | sort | uniq -c 12 2001:504:27::1e49:0:1 1 2001:504:27::3823:0:2 1 2001:504:27::39:0:1 1457433 2001:504:27::5adc:0:1 3 2001:504:27::6478:0:1 1457369 2001:504:27::8e16:0:1 1 2001:504:27::9dbe:0:1 5 2001:504:27::9dbe:0:2 1179733 2001:504:27::b7f8:0:1 1176975 2001:504:27::d15d:0:1 4 2001:504:27::e4f:0:1 1 2001:504:27::f756:0:1 1331747 2001:504:27::f7a2:0:1 1179735 206.108.255.101 7494 206.108.255.119 1954 206.108.255.120 3 206.108.255.137 3 206.108.255.161 1331745 206.108.255.168 1457437 206.108.255.17 2 206.108.255.176 8 206.108.255.185 11 206.108.255.3 6 206.108.255.46 1457345 206.108.255.53 4 206.108.255.92 -- Richard

MICE Core Switch Card Upgrade
by Richard Laager Feb. 8, 2024

Feb. 8, 2024

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
