<br>
we are having recently problems with connection to RouteServers.<br>
Well, RS'es are configured to add their AS as first in path, so connection is possible.<br>
<br>
However, sometimes it happens, that all next hops are set as RouteServer IP addresses (and so traffic is dropped by RS).<br>
<br>
It happens more often, when we have iBGP between 2 SE100, and both SE100 are connected paralelly to the same route-servers (via the same VLAN, but different IP addresses from the same /23 network).<br>
<br>
If there are some problems with RSes, or one of sessions goes down - SE100 with 6.2.1.4 locks next hop as RS address.<br>
SoftClear, clear, whatever - doesn't help.<br>
Restart of bgp process, rib process - also, no result.<br>
<br>
The only solution is to remove IP address from IX interface (PLIX), clear BGP sessions (with 2 RSes, on both the same problem same time).<br>
Then add this IP back to PLIX interface and commit.<br>
<br>
(and in meantime, SEOS sends some ARP requests from other VLANs to PLIX vlan !?!?)<br>
<br>
<br>
<br>
Is it a bug or there is some condition at which it is possible to replace proper next-hop with RS IP ?<br>
<br>
(RSes advertise proper next-hop addresses)<br>
<br>
Regards,<br>
Marcin<br>
