Active Select this check box to advertise routes that were learned from the indicated
source.
• If you select this for RIP, the ZyWALL advertises routes learned from RIP to
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.
Route This field displays other sources of routing information that the ZyWALL can
advertise in the OSPF AS.
Type 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.
Metric Type the external cost for routes provided by the indicated source. 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.
