<pre>Hi everyone,
It looks like we've managed to find another strange problem with BGP on
SEOS. In the night one of our peers session started to flap with
following message:
May 29 10:52:01: [0001]: %BGP-6-INFO: 195.149.233.1 UP
May 29 10:52:15: [0001]: %BGP-6-INFO: 195.149.233.1 DOWN - Notification sent
May 29 10:52:15: [0001]: %BGP-6-INFO: 195.149.233.1 send NOTIFICATION:
3/11 (update: malformed ASPATH) with 21 byte data. mxReadMs=1555
It does not look like previously mentioned attribute flag error. Does
anyone had something simillar ? It is a session with route server, so i
know about "no enforce first-as" option and it is turned on, it was
working fine till this night with no configuration change on our side.
"show bgp malform update" looks like this:
May 29 10:52:15 Malformed UPDATE msg (nbr 195.149.233.1, context
0x40080001, 77 bytes, repeated 5 times, reason: Invalid msg) -
ffff ffff ffff ffff ffff ffff ffff ffff 004d 0200 0000 3240 0101 0040
0212 0104 0000 17d9 0000 183e 0000 1840 0000 1967 4003 04c3 95e9 6480
0404 0000 0000 c007 0800 0073 5fc3 95ef ff16 c395 ec
SEOS version SEOS-12.1.1.11p7-Release
Thanks in advance,
Best regards,
