OSPF Parameters

The OSPF Parameters window displays the following fields:

• Administrative Status — The OSPF administrative status in the router. The field options are the following:

• Enabled — The OSPF process is active on at least one interface.

• Disabled — The process is not active on any interface.

• Router ID — The router ID number. To ensure uniqueness the router ID must be equal to one of the router IP addresses. By default, the router ID takes the IP Interface Address. Reset the device to allow changes in the router ID to take effect.

• 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 LS database, and to compare the LS database of two routers.

• Leak RIP Routes — Controls the route redistribution 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 route redistribution 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 direct route redistribution which are external to OSPF into OSPF. If this parameter is enabled all external routes are advertised into OSPF as external routes.

To configure the NMS to support the OSPF routing protocol:

1. On the Area Table define an Area ID number.

2. Enable the OSPF Protocol.

3. For each interface, define its status in connection with the OSPF.

The NMS supports up to 120 IP interfaces and up to 362 neighbors on one Area. OSPF supports leaks to RIP1 and RIP2. NMS configured to support OSPF does not support virtual links.
