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 20.20.20.0/22
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 20.20.20.0/22

First of all, why are you using NSSA instead of just stub? Are you importing any routes into Area 0 from  Area 10?

You can have more than one network per area, just try to summarize properly at ABR.

No I am not importing any routes into Area 0. The reason why I am using NSSA instead of just Stub is due to the existing restriction I have at present.
Ok got your point . I can have additional network per area.
Thanks

OSPF areas are not limited to one network.

Thanks.
In the above scenario how can i insert the 20.20.20.0/22 network into the existing NSSA Area.
Can i have the same area for this network or should i use different area for this new network.

Is it recommended to use static route or use OSPF only.

Configuring network clients can be a chore, especially if there are a large number of them or a lot of itinerant users.  DHCP dynamically manages this process, much to the relief of users and administrators alike!
Microservice architecture adoption brings many advantages, but can add intricacy. Selecting the right orchestration tool is most important for business specific needs.
