External Routes

To view OSPF external route statistics:

1. Select the Statistics menu from the Web UI.
2. Expand the System node from the navigation pane (on the left-hand side of the screen). The System node expands to display the RF Domains created within the managed network.
3. Expand an RF Domain node, select a controller or service platform, and select one of its connected access points. The selected device's statistics menu displays in the right-hand side of the screen, with the Health tab selected by default.
4. Expand the OSPF from the left-hand side of the UI.
5. Select the Routes > External Routes tab.
   The Statistics > Controller > OSPF > Routes > External Routes screen displays.

   

   

   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 route 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.
