ZyWALL USG 20/20W User's Guide
DESCRIPTION
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.
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.
