Greetings. I am in the process of turning up bgp with a customer and have run into the following problem. The customer is using a Cisco router with ios 11.1.20. Im using a GRF400. The session wont establish and this is what the log is showing: Sep 18 15:50:59 Sep 18 15:50:59 BGP RECV 209.239.69.1+32617 -> 206.84.235.254+179 Sep 18 15:50:59 BGP RECV message type 1 (Open) length 37 Sep 18 15:50:59 BGP RECV version 4 as 11042 holdtime 180 id 209.239.64.254 authcode 8 Sep 18 15:50:59 BGP RECV Auth data (8 bytes): 02 06 01 04 00 01 00 01 Sep 18 15:50:59 Sep 18 15:50:59 bgp_get_open: peer 209.239.69.1+32617 (proto): unknown athentication code 8 used Sep 18 15:50:59 Sep 18 15:50:59 BGP SEND 206.84.235.254+179 -> 209.239.69.1+32617 Sep 18 15:50:59 BGP SEND message type 1 (Open) length 29 Sep 18 15:50:59 BGP SEND version 4 as 4200 holdtime 180 id 206.84.235.254 authcode 0 Sep 18 15:50:59 Sep 18 15:50:59 Sep 18 15:50:59 BGP SEND 206.84.235.254+179 -> 209.239.69.1+32617 Sep 18 15:50:59 BGP SEND message type 3 (Notification) length 21 Sep 18 15:50:59 BGP SEND Notification code 2 (Open Message Error) subcode 4 (unsupported authentication code) Sep 18 15:50:59 Sep 18 15:50:59 NOTIFICATION sent to 209.239.69.1+32617 (proto): code 2 (Open Message Error) subcode 4 (unsupported authentication code) data it appears that the cisco is sending us an authcode that we don't recognize. Is there a way to prevent the cisco from sending the authcode 8 or change the authcode to something more civilized, like authcode 0. The customer is willing to change their IOS version if necessary but it is not the preferred resolution. Any suggestions on how I could get this to work? *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* | Harold Willison AGIS Network Engineering | * Senior Network Engineer 313-730-5151 * | [email protected] 313-730-1130 x-5649 | | [email protected] 24 hours a day, 7 days a week | | http://www.agis.net | \*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*/
