Table 99 Configuration > Network > Routing Protocol > OSPF LABEL DESCRIPTION OSPF Router ID Select the 32-bit ID the ZyWALL uses in the OSPF AS. Default - the highest available IP address assigned to the interfaces is the ZyWALL's ID. Redistribute Active RIP Type User Defined - enter the ID (in IP address format) in the field that appears when you select User Defined. 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. 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) Metric Active Static Route 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. Select this to advertise routes that were learned from static routes. The ZyWALL advertises routes learned from static routes to all types of areas. 402 ZyWALL USG 300 User's Guide
