Prefix Suppression Display whether prefix-suppression is enabled or disabled. Maximum Paths The maximum number of paths that OSPF can report for a given destination. Default Metric Default value for redistributed routes. Maximum Routes The maximum number of routes that OSPF can support. Stub Router Configuration Indicates whether stub router is configured. BFD Mode Indicates whether BFD is enabled or disabled. Default Route Advertise Indicates whether the default routes received from other source protocols are advertised or not. Always Shows whether default routes are always advertised. Metric The metric for the advertised default routes. Metric Type Shows whether the routes are External Type 1 or External Type 2. Number of Active Areas The number of active OSPF areas. An "active" OSPF area is an area with at least one interface up. ABR Status Shows whether the router is an OSPF Area Border Router. ASBR Status Reflects whether the ASBR mode is enabled or disabled. Enable implies that the router is an autonomous system border router. The router automatically becomes an ASBR when it is configured to redistribute routes learnt from other protocols. The possible values for the ASBR status is enabled (if the router is configured to redistribute routes learned by other protocols) or disabled (if the router is not configured for the same). Stub Router Status When OSPF runs out of resources to store the entire link state database, or any other state information, OSPF goes into stub router mode. As a stub router, OSPF re-originates its own router LSAs, setting the cost of all non-stub interfaces to infinity. To restore OSPF to normal operation, disable and re-enable OSPF. External LSDB Overflow When the number of non-default external LSAs exceeds the configured limit, External LSDB Limit, OSPF goes into LSDB overflow state. In this state, OSPF withdraws all of its self-originated non-default external LSAs. After the Exit Overflow Interval, OSPF leaves the overflow state, if the number of external LSAs has been reduced. External LSA Count Shows the number of external (LS type 5) link-state advertisements in the linkstate database. NETGEAR M4500 Series Switches CLI Command Reference Manual 925
