How to filter VNI’s between two Nexus EVPN Multisite Fabrics?

[jackjone4646]

Hi Folks,

I’m wanting to bring up VTEP peering between two Data Centres that use the Multisite design. The pickle I’m in is that by default everything is allowed to be advertised over the VTEP peering.

How would I only allow VNI 10001 to be advertised and restrict the other 500 that’s configured?

In case of Multisite design you need to specify

multisite ingress-replication 

under extended VNI.

You can configure it only on VNI which you want to extend.

Also good presentations regarding Multisite
