Router-ID are following: 81.91.X.X 91.194.X.X 82.198.X.X
I don't have bgp best path compare-routerid enabled also. On 11/10/11 13:34, Saku Ytti wrote:
You don't have router-id there, maybe one of the conditions why router-id is being compared is taking force. Would router-id explain the preference? http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094431.shtml ------ When both paths are external, prefer the path that was received first (the oldest one). Skip this step if any of these items is true: - You have enabled the bgp best path compare-routerid command. - The router ID is the same for multiple paths because the routes were received from the same router. - There is no current best path. The current best path can be lost when, for example, the neighbor that offers the path goes down. ------- On 11 October 2011 12:18, Nikolay Shopik<[email protected]> wrote:Hi, I have rather strange best path selection. We have 3 uplinks, AS_PATH to one of prefix is same for all 3 prefixes, so my assumption it will use oldest one, because everything else is same. Except one thing I notice one of uplinks send us metric, while two others does not. Here is example, first one is oldest, second is youngest, but it still choices last one. While should choice first, because everything else is same. 39792 9002 25532 Origin IGP, metric 400, localpref 100, valid, external Community: 39792:3000 39792:3004 41095 9002 25532 Origin IGP, localpref 100, valid, external Community: 41095:2000 41095:2001 41095:2100 41095:2101 30733 9002 25532 Origin IGP, localpref 100, valid, external, best Community: 9002:0 9002:64667 30733:6022 I start to believe it using metric anyway, while I don't use that option.
