Thread Index [isp-bgp] RE: Sample BGP Config
Hi, I have a rather basic question, If i multihome with two ISP's and one link goes down, will the traffic be routed immediately to the links that is up or does this take little time. ( wait before router down is propagated ) Regards, Cor The rest i assume you know how to configure yourself. /Carl ------- Ursprungligt brev ------- Från: chris@... Datum: Tue, 15 Jul 2003 14:58:48 -0700 Michael, Thanks for the response. The example I read was "Load Sharing when Multihomed to Two ISPs via Multiple Local Routers" The outbound traffic policy in this example limits traffic to one of the two providers unless there is a failure. The outbound traffic policy is as follows: Traffic destined to AS 300 goes via the R1 - ISP(A) link. Traffic destined to AS 400 goes via the R2 - ISP(B) link. All other traffic should prefer default route 0.0.0.0 via the R1 - ISP(A) link. If the R1 - ISP(A) link fails, all traffic should go via the R2 - ISP(B) link. I'd like to have outbound traffic take the shortest path if both ISP's are up and fail over to the other ISP if one ISP link fails. Christopher J.

Perhaps specify what you didnt like... As the answer will be based on Cisco's docs. -----Original Message----- From: Christopher J. Wolff [mailto:chris@...Sent: Wednesday, 16 July 2003 9:47 a.m. To: isp-bgp@isp-bgp.com Subject: [isp-bgp] Sample BGP Config Hello, I'm looking for a couple of sample cisco configs that illustrate two multihomed routers connected by an IGP session. For example; Router 1----------Isp 1 | | IGP | | Router 2----------Isp 2 I read the Cisco scenarios for multihomed networks documents but I didn't like what I read. Thank you in advance. C.J.
