DESCRIPTION

OSPF Router ID

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

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

 

appears when you select User Defined.

Active RIP

Select this to advertise routes that were learned from RIP. The

 

ZyWALL advertises routes learned from RIP to Normal and NSSA

 

areas but not to Stub areas.

 

 

Type

Select how OSPF calculates the cost associated with routing

 

information from RIP. 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.

 

 

Metric

Type the external cost for routes provided by RIP. 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.

 

 

Active Static

Select this to advertise routes that were learned from static routes.

Route

The ZyWALL advertises routes learned from static routes to all types

 

of areas.
