How do i configure an PRI interface, so that it acts as a backup interface(will dial to different network) to 2 E1 links. I am using OSPF and both the E1 links are in load balancing fashion. I cannot configure multilink because i am using a E1 to V.35 converter to connect the E1 to Serial interface in the router. It was not working when i configured multilink. I want the backup PRI to take over only if both the links go down. Please Help..
Just place a floating static route in your config and define interesting traffic so that your link is not kept up indefinately. You can search CCO for more examples but since your using ospf your "show ip route" would look like the following;
10.10.10.1 via E1 (110/10)
via E2 (110/10)
When the routes drop, the floating static would kick in and look like the following;
10.10.10.1 via PRI1 (200/100)
There are several ways to accomplish what your looking for but this is my favorite method. Hope this helps
