BGP session reset

Greeting

I have setup an eBGP session to a Cisco 2801 CE router. The BGP session establish, however, the session keeps resetting after  90 sec which is the BGP keepalive holdtime value.

Testing:

On the PE router I found that the OutQ doesn't clear = 22 when doing a "sh ip bgp x.x.x.x summary" - Session reset at 1:30

When I filter the amount of routes advertized to the CE neighbor with the "neighbor x.x.x.x prefix-list out" - I see the OutQ clear = 0 and the BGP session remains up.

Number of NRLI advertized without prefix filter = 172

Number of NLRI after filter = 52

I would welcome your suggestions as to why the OutQ doesn't clear.

Regards,

Werner

Hi,

I guess there might be  neighbor maximum-prefix configured on the CE router?

See http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a008010a28a.shtml

for details.

HTH,

Milan
