DESCRIPTION
Select this to advertise routes that were learned from RIP. The ZyWALL/USG
advertises routes learned from RIP to Normal and NSSA areas but not to Stub
areas.
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.
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.
