We would like to mix the OSPF and HSRP to provide a better service to custemers. The solution is following:
There are two uplink routers, R1 and R2. Each uplink router connects to one distribution layer router (R3 and R4). Below is the configuration for your reference.
Is it possible to build a "ospf nei" between two floating ip ONLY (192.168.1.1 and 192.168.1.4)? there is no "ospf nei" between the direct connection of each router. how to config it to achieve this approach?
There is only one FIB. If one of uplink routers is failure, the converging time should be very fast (depend on the HSRP). It would be less service impact on user. is it correct?
I try to add the ip segment (192.168.1.0/29), the client side router can establish two nei. In R3, there are two nei (R1 and R2). The opposit nei IP is 192.168.1.2 and 192.168.1.3. It cannot build nei between two floating IP addresses.
I agree with the other poster that your OSPF configuration doesn't look like complete, as in order to create OSPF adjacencies you need to add a network ... area 0 statement for the IP subnets between R1-R3 and R2-R4.
