Administrative Status – The administrative status of the OSPF in the router. Enabled means that the OSPF process is active on at least one interface. Disabled means the process is not active on any interfaces.

Router ID – The ID number of the router. To ensure uniqueness the router ID should equal one of the router IP addresses.

Number of External LSAs – The number of external Link-State Advertisements in the link-state database.

External LS Checksum Sum – The sum of LS checksums of external LS advertisements contained in the LS database. Use this sum to determine if there has been a change in a router's LS database, and to compare the LS database of two routers.

Leak RIP Routes – Controls the redistribution of routes from RIP into OSPF. When this parameter is enabled, all routes inserted into the IP routing table via SNMP are advertised into OSPF as external routes.

Leak Static Routes – Controls redistribution of routes from static routes to RIP. When this parameter is enabled, all static routes learned via static are advertised into RIP.

Leak External Direct Routes – Controls redistribution of direct routes which are external to OSPF into OSPF. If this parameter is enabled all external routes are advertised into OSPF as external routes.
