I'm thinking about doing a routed access layer datacenter design with OSPF.
- couple TORs switches from every rack connect to a pair of core switches via l3 links
- every rack is it's own totally stubby area. About 200 racks, total about 400 switches. TORs are either 4948s or nexus 3k
- Core Acts as ABRs. Cores are chassis bases high end boxes (nexus 7k, or juniper 9200 etc)
The idea is to just have a default on the TORs and keep the LSA database small, hence unique area per rack. Should i be concerned about ABRs (cores) generating that many type 3 LSA for different areas?
