OSPF
Refer to the Routes tab to assess the status of OSPF Border Routes, External Routes, Network Routes and Router Routes.
To view OSPF route statistics:
1. Select the Statistics
2. Select System
access point for statistical observation.
3. Select OSPF.
4. Select the Routes
An area border router (ABR) connects (links) more than one area. Usually an ABR is used to connect non-backbone
areas to the backbone. If OSPF virtual links are used an ABR will also be used to connect the area using the virtual link
to another non-backbone area. Border routes use internal OSPF routing table entries to an ABR or Autonomous System
Boundary Router (ASBR). Border routers maintain an LSDB for each area supported. They also participate in the
backbone.
5. Refer to External Routes
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,
