Your article with tags moved me in the correct direction and I appreciate the posted comments on aggregation. My problem was simple, can one failover a remote iBGP spoke location and have BGP act in a similar “Link State” protocol as its Core Router? Moreover, can this solution not export iBGP routes in and out of EIGRP or OSPF WAN routing protocols? <BR/>Without telling you the entire whole story, the answer is “Yes it can be completed.” However, it quite complicated and one needs to be careful. The solution utilizes route maps, tags on static routes and BGP Backdoor commands. I am able to fail a remote MPLS location (running iBGP) and have its IP Traffic traverse an IPSEC Tunnel across the Internet and into an ASA. At the core router, I point that backup traffic to that ASA. While the failover time is not instantaneous, it does resume in less than 30 seconds. <BR/><BR/>Network Details;<BR/>Remote Site1: 10.1.60.1/24 and Remote Site2: 10.1.70.1/24<BR/>Core Router: 10.1.2.1/24 with Failover ASA: 10.1.2.5/25<BR/><BR/>Here is what the Core Route configuration looks like;<BR/>!<BR/>router bgp 111<BR/>network 10.1.60.0 mask 255.255.255.0 route-map NoStatic backdoor<BR/>network 10.1.70.0 mask 255.255.255.0 route-map NoStatic2 backdoor<BR/>!<BR/>ip route 10.1.60.0 255.255.255.0 10.1.2.5 220 tag 220<BR/>ip route 10.1.70.0 255.255.255.0 10.1.2.5 225 tag 225<BR/>!<BR/>route-map NoStatic permit 10<BR/>match tag 220<BR/>set metric 220<BR/>!<BR/>route-map NoStatic2 permit 20<BR/>match tag 225<BR/>set metric 225<BR/>!<BR/>If one would wish to speak directly, shoot me an email @ timothy.barko@kimballcorp.com and I can explain in detail how it was completed with the complete details on my Failover Solution.Timothyhttp://www.blogger.com/profile/14568042604208385006noreply@blogger.comtag:blogger.com,1999:blog-23021255.post-82595270992786883132008-02-25T23:34:00.000+01:002008-02-25T23:34:00.000+01:002008-02-25T23:34:00.000+01:00dont forget to also use the "local-as" community if you are using confederations as no-export refers to the confederation and not the subconfederation.Anonymousnoreply@blogger.com
