Hello,<br>

As I found, the most probable cause is aggregator = 0.0.0.0<br>

(this update i.e. drops down all external sessions on other SEOS 6.4.1.1)<br>

More HEX dump below, this seems to be a very, very serious problem.<br>
Same problem with 6.3.x.y. series..<br>

08 - of 8 bytes<br>
0000611f - from AS 24863<br>
00000000 - aggregated by 0.0.0.0<br>
<br>
According to RFC4271, sec 5.1.7:<br>
<br>
AGGREGATOR is an optional transitive attribute, which MAY be included<br>
in updates that are formed by aggregation (see Section 9.2.2.2). A<br>
BGP speaker that performs route aggregation MAY add the AGGREGATOR<br>
attribute, which SHALL contain its own AS number and IP address. The<br>
IP address SHOULD be the same as the BGP Identifier of the speaker.<br>
<br>
It is possible that SEOS considers 0.0.0.0 to be an invalid BGP<br>
identifier and therefore an impossible aggregator<br>
<br>
For reference, this update covers the following prefixes:<br>
<br>
<a href="http://41.178.0.0/24" target="_blank">41.178.0.0/24</a><br>
<a href="http://41.196.4.0/22" target="_blank">41.196.4.0/22</a><br>
<a href="http://41.196.8.0/22" target="_blank">41.196.8.0/22</a><br>

<br>
<br>
with AS_PATH 24724 15412 24863<br>
<br>
Since none of my SEOS boxes carry a full table can another SEOS operator<br>
with a full table confirm if they have these prefixes (and if so, what<br>
it shows as aggregator)<br>
<br>
I can tell you in Cisco IOS, I accept these prefixes.<br>

Is there any possibility to ignore malformed updates instead of<br>
dropping down whole session ?<br>
