Table 137 Configuration > Network > Routing Protocol > OSPF LABEL DESCRIPTION OSPF Router ID Select the 32-bit ID the Zyxel Device uses in the OSPF AS. Default - the first available interface IP address is the Zyxel Device's ID. Redistribute Active RIP Type User Defined - enter the ID (in IP address format) in the field that appears when you select User Define. Select this to advertise routes that were learned from RIP. The Zyxel Device 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. ZyWALL ATP Series User's Guide 352
