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

and it can be between 1 and 16777214.
