Select the 32-bit ID the ZyWALL uses in the OSPF AS.

Default - the highest available IP address assigned to the interfaces is

the ZyWALL's ID.

User Define - enter the ID (in IP address format) in the field that

appears when you select User Define.

Select this check box to advertise routes that were learned from the

indicated source.

If you select this for RIP, the ZyWALL advertises routes learned from

RIP to Normal and NSSA areas but not to Stub areas.

If you select this for static routes, the ZyWALL advertises routes

learned from static routes to all types of areas.

This field displays other sources of routing information that the ZyWALL

can advertise in the OSPF AS.

Select how OSPF calculates the cost associated with routing information

from the indicated source. Choices are: Type 1 and Type 2.

Type 1 - cost = OSPF AS cost + external cost (Metric)

Type 2 - cost = external cost (Metric); the OSPF AS cost is ignored.

Type the external cost for routes provided by the indicated source. The

metric represents the "cost" of transmission for routing purposes. The

way this is used depends on the Type field. This value is usually the

average cost in the OSPF AS, and it can be between 1 and 16777214.
