DESCRIPTION
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.
This section displays information about OSPF areas in the ZyWALL.
