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 Route Select this to advertise routes that were learned from static routes. The ZyWALL
advertises routes learned from static routes to all types of areas.
Type Select how OSPF calculates the cost associated with routing information from static
routes. 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 static routes. 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.
