OBJECT-TYPE

The router's support for type-of-service rout- ing.

OBJECT-TYPE

The number of new link-state advertisements that have been originated. This number is in- cremented each time the router originates a new LSA.

OBJECT-TYPE

The maximum number of non-default AS- external-LSAs entries that can be stored in the link-state database. If the value is -1, then there is no limit. When the number of non-default AS-external-LSAs in a router's link-state database reaches nsOspfExtLsdbLimit, the router enters Overflow- State. The router never holds more than nsOspfExtLsdbLimit non-default AS-external-LSAs in its database. OspfExtLsdbLimit MUST be set identically in all routers attached to the OSPF backbone and/or any regular OSPF area. (i.e., OSPF stub areas and NSSAs are excluded).

OBJECT-TYPE

Bit 0, if set, indicates that the router can forward IP multicast datagrams in the router's directly attached areas (called intra-area mul- ticast routing). Bit 1, if set, indicates that the router can forward IP multicast datagrams between OSPF areas (called inter-area multicast routing). Bit 2, if set, indicates that the router can forward IP multicast datagrams between Auto- nomous Systems (called inter-AS multicast rout- ing). Only certain combinations of bit settings are allowed, namely: 0 (no multicast forwarding is enabled), 1 (intra-area multicasting only), 3 (intra-area and inter-area multicasting), 5 (intra-area and inter-AS multicasting) and 7 (multicasting everywhere). By default, no mul- ticast forwarding is enabled.

OBJECT-TYPE

The variable nsOspfAreaSummary controls the im- port of summary LSAs into stub areas. It has no effect on other areas.

If it is sendAreaSummary, the router will both summarize and propagate summary LSAs.
