Contracts between Multi Site APIC

[sandyblaza]

I have tenants that reside on APIC site A and APIC site B (multi-site), and they can communicate via OTV.

But I got problem on server return traffic of APIC site B to APIC site A, my question is it's possible to create contract between to site?

You're using OTV as your DCI?  

There's no such thing as a contract between sites.  You create contracts between EPGs (in separate sites) or you can stretch the same EPG across sites.  If you want L2 connectivity between the sites, ensure the BD defined in Msite is L2 Stretch enabled.

Hi @sandyblaza 

There are multiple ways on how you can configure the BDs/EPGs when it comes to ACI Multi-Site. The most common ones are these:

• Stretched Bridge Domain with Layer 2 Broadcast Extension

• Stretched Bridge Domain with No Layer 2 Broadcast Extension

• Stretched EPG Across Sites

• Stretched VRF with Inter-Site Contracts

Stay safe,
