Router2(config)# ip as-path access-list 15 permit ^$ Router2(config-if)# description connection to internal network, ASN 65500

Router2(config-if)# description connection to ISP #2, ASN 65520 And because these two routers are both members of the same AS, they also must have an iBGP connection: Then the second router connects to the second ISP, which uses ASN 65520. Router1(config-router)# no synchronization Router1(config-router)# neighbor 192.168.1.5 filter-list 15 out Router1(config-router)# neighbor 172.18.5.3 next-hop-self Router1(config)# ip as-path access-list 15 permit ^$ Router1(config-if)# description connection to internal network, ASN 65500 Router1(config-if)# description connection to ISP #1, ASN 65510 The first router has a link to the first ISP, whose ASN is 65510:Įnter configuration commands, one per line. In this example, we have two routers in our AS, which has ASN 65500. You want to connect your network to two different ISPs using two routers to eliminate any single points of failure.
