Figure 13-53 Access Point - OSPF External Routes tab
External routes are external to area, originate from other routing protocols (or different OSPF processes) and are inserted
into OSPF using redistribution. A stub area is configured not to carry external routes. Each external route can be tagged by
the advertising router, enabling the passing of additional information between routers. Each external route can also be
tagged by the advertising router, enabling the passing of additional information between routers on the boundary of the
autonomous system.
The External Routes tab displays a list of external routes, the area impacted, cost, path type, tag and type 2 cost. Cost
factors may be the distance of a router (round-trip time), network throughput of a link, or link availability and reliability,
expressed as simple unit-less numbers. This provides a dynamic process of traffic load balancing between routes of equal
cost.
