Additionally, you may have interest in Cisco's Primary and Backup WAN Links Using Cisco Optimized Edge Routing.
There are two types of links: primary and backup. The desired behavior for the links is listed below:
· Traffic will move to a secondary link only if all the primary links meet one of the following conditions:
-The link is unavailable
-Routes are not reachable
-Utilization is above the threshold
· Traffic will move back from a secondary link if the primary links have enough head room to accommodate traffic and the prefixes are reachable
· Prefixes that are unreachable on a link (primary or secondary) will be moved to a reachable link (primary or secondary)
