ACI - Multiple L3Outs with same OSPF process

HI,

 

I am trying to have the DCI routers and MPLS routers as OSPF neighbors with ACI.

Tried configuring multiple L3Outs on the border leaf with same OSPF process ID and it won’t allow me to. Per Cisco docs this is not allowed. Do I have to have separate OSPF process for each L3Out? Is there no way to work with a single OSPF process?

Hi Ninja.  Your intuition is correct.  You can have multiple, independent routing adjacencies under the same L3Out (all using the same protocol of course).  Think of the L3Out object as a "routing process" like in a traditional router.   You just need to add additional Logical Interface Profiles under your existing L3Out. 

Hope it helps.
