Inter VRF route leaking. Configuring subnet in EPG vs subnet in BD
i want to configure route leaking between two different VRF in different Tenant. i am aware the process but bit confused while configure subnet in provider side EPG. the subnet which i want to configure in EPG (Gateway IP/24) is also already configured in my BD. The question here is can I configure same subnet with same gateway in BD and EPG under same tenant?
Yes, its fine to configure the subnet in both places. The reason the subnet needs to be defined specifically under the EPG is so the fabric can determine which sclassIDs (EPGs) within the providers subnet should be leaked into the consumer's VRF. Keep in mind in a network Centric design, there could be multiple EPGs assigned to the same BD subnet, and we're not trying to give access to every EPG using the Providers BD subnet, just a subset of EPGs that may be using it.
