Hello CSC,
Looking for some advice and also to see if this is a common scenario. All the VXLAN guides I see refer to Spine/Leaf which this is not.
We have our core switching (9500 stackwise virtual) with 4 nexus connected at L2 (2 x VPC domain). All GWs for current VLANs are SVIs on the core switching. We have the exact same setup at our other DC. We have a DCI between the DCs. Can support jumbo frames etc..
There is a requirement to get VXLAN configured between the two DCs. My understanding is that the existing GWs for non vxlan vlans will stay on the 9500 stack and any VXLAN VLANs will have their GW on the NEXUS. Is this a valid interim setup? Assume I would need some border device role to route between old and VXLAN subnets?
For the underlay is it best to cable additional ports and use these for underlay rather than run SVIs across the existing layer 2 trunks between Nexus and Core?
Any pointers/advice welcome.
Thanks
