Fixed.<br>
The problem was located in TPIX, and had been fixed.<br>
And that was not a SEOS fault. SEOS behaves correctly. Question is
why Juniper passed malformed update...<br>

everyone,
<br>
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:
<br>
May 29 10:52:01: [0001]: %BGP-6-INFO: 195.149.233.1 UP
<br>
May 29 10:52:15: [0001]: %BGP-6-INFO: 195.149.233.1 DOWN -
Notification sent
<br>
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
<br>
<br>
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.
<br>
<br>
"show bgp malform update" looks like this:
<br>
May 29 10:52:15 Malformed UPDATE msg (nbr 195.149.233.1, context
0x40080001, 77 bytes, repeated 5 times, reason: Invalid msg) -
