I have the attached OSPF Design. There is Area 0 (Backbone) & there is AREA 10 which is NSSA. I have the subnet 10.10.10.0/22 in this area. I have been exhausted with the existing subnet & I would require to use another subnet say 22.214.171.124/22
The OSPF is established between the L3 Switches & the Routers using IP from the 10.10.10.0/22 subnet.
I would like to know is it possible to use another subnet in the same NSSA Area (Area 10)
If possible should i need to have another OSPF neig between the L3 switches & the routers from the subnet 126.96.36.199/22
Request your inputs.
