Router ID (ospfRouterId)

32-bit integer that uniquely identifies the router in an autonomous system. By convention, the default value of this object is one of the router's IP interface addresses.

OSPF Admin. Status (ospfAdminStat)

Administrative status of OSPF in the router. When the value of this object is "enabled", the OSPF process is active on at least one interface. When the value of this object is "disabled", OSPF is disabled on all interfaces.

OSPF Version No. (ospfVersionNumber)

Current version number of the OSPF protocol is 2.

Area Border Router (ospfAreaBdrRtrStatus)

Indicates whether this router is an area border router.

AS Border Router (ospfASBdrRtrStatus)

Indicates whether this router is an autonomous system border router.

AS-external-LSA CheckSum Sum (ospfExternLSACksumSum)

32-bit unsigned sum of the LS checksums of the external link-state advertisements contained in the link-state database. This sum can be used to determine if there has been a change in a router's link- state database, and to compare the link-state database of two routers.

Type of Service Support (ospfTOSSupport)

Indicates the router's support for type-of-service routing.
