[f-nsp] OSPF examples in ip-subnet vlans

Fri Aug 28 14:42:21 EDT 2009

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?
I understand I have to make the core an ABR. Not sure how I go about setting
that feature.

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?

here's my configs - thanks for looking :)
