Metric Shows the metric for the advertised default routes. If the metric is not configured, this field is not configured. Metric Type Shows whether the metric for the default route is advertised as External Type 1 or External Type 2. Number of Active The number of OSPF areas to which the router is attached on Areas interfaces that are up. ABR Status Shows whether the router is an OSPF Area Border Router. ASBR Status Indicates whether the router is an autonomous system border router. Router automatically becomes an ASBR when it is configured to redistribute routes learned from another protocol. The possible values for the ASBR status is enabled (if the router is configured to re-distribute routes learned by other protocols) or disabled (if the router is not configured for the same). Stub Router OSPF enters stub router mode, as described in RFC 3137, when it encounters a resource limitation that prevents it from computing a complete routing table. In this state, OSPF sets the link metrics of non-stub links in its own router LSAs to the largest possible value, discouraging other routers from computing paths through the stub router, but allowing other routers to compute routes to destinations attached to the stub router. To restore OSPF to normal operation, resolve the condition that caused the resource overload, then disable and reenable OSPF globally. External LSDB Overflow OSPF enters this state when the number of external LSAs exceeds a configured limit, as described in RFC 1765. External LSA Count Shows the number of external (LS type 5) link-state advertisements in the link-state database. External LSA Checksum Shows the sum of the LS checksums of external link-state advertisements contained in the link-state database. AS_OPAQUE LSA Shows the number of AS Opaque LSAs received. Count AS_OPAQUE LSA Sum of the checksums of all AS Opaque LSAs in the link state Checksum database. New LSAs Originated Shows the number of link-state advertisements that have been originated.
