We are building three small data centers. BGP and OSPF will be introduced to route the traffic.
I have a question about configuring OSPF.
We don't have many routers but only two or three routers in each DC. When configuring the OSPF area on the routers,
can I put all the routes in the same area, like area 0? Or they have to be in different areas, for example, routers in DC0 with area 0,
routes in DC1 with area 1?
Thanks in advance for your help.
