Hey folks, I am designing an OSPF environment in ACI. My Area 0 is on leafs 101 and 102. Area 1 is on leaf 103 and 104. (pic attached)
Basics of OSPF states that all areas should be connecting to Area 0 (backbone), otherwise you need some extra techniques like virtual-link or something to join them. Virtual-link is NOT supported in ACI.
So I am wondering will this work OR do I need to move Area 1 to leaf 102, so that now leaf 102 is the ABR (part of Area0 and 1).
I didn't get the purpose of the Router in Area 1 and 0. Which is the underlying control panel Routing protocol? Please share some more information.
As there is no issue, you can use the areas same as you mentioned in the diagram. Again I am still not sure about the underlying routing protocol. If you are using ISIS or BGP then make a sham-link between both areas.
