Referring to campus networks where direct fiber connectivity exists between routers and CORE but the network is too large/complex for a collapsed-core scenario thus entailing the need for an IGP. A non-Cisco SE came in to sell us a VXLAN solution for...

It took putting it in writing to see the error of my ways. I had reversed the netmask in the range command. Instead of /76 I needed /52. Once I made the change I saw the desired behavior just like with IPv4/OSPFv2.

Sorry, could you rephrase that please?
