I'm looking for some examples of OSPF configuration in a working ip-subnet vlan environment. I am setting up a core 0.0.0.0 switch that spokes to four other foundry 8k/15k bigiron swtiches. I haven't used OSPF yet. I configured the core with loopback 1 ip address 0.0.0.0 Do I use that same area ip on spoke foundrys or do they all use a different/identical address area such as 10.1.1.1 for each?<div>
<br></div><div>I understand I have to make the core an ABR. Not sure how I go about setting that feature. </div><div><br></div><div>also, this is the first time I'm using ip-subnet vlans. I'm not sure if i can use the same ip-subnets on each switch but have different virtual interface ips for each of these ip-subnets. Where it might be tricky is that i don't need tagged ports for all our devices and I don't know if I will need to use tagged ports and dual-mode across all the ports in order for the traffic from the edge ip-subnet vlans to cross over to the core or not?</div>
