ISN Rtr Role

Nexus Dashboard

Configure Border Gateway Roles

Assign border gateway roles to enable proper inter-site routing and VXLAN forwarding.

BGW Configuration

Border Gateway switches require specific role configuration to function as inter-site VXLAN gateways, including MP-BGP EVPN peering and overlay routing between fabrics.

Multi-Site Architecture

Proper role configuration ensures border gateways can extend VNIs across sites, maintain tenant isolation, and provide optimal traffic forwarding for inter-site workload communication.

Step 1 - Set ISN Router Role

Set the role of the external device, Core-Rtr, correctly:

  1. Click Inventory
  2. Locate and select the checkbox for Core-Rtr
  3. Click Actions
  4. Click Set Role in the dropdown menu


  5. You may need to Scroll Down to find Core Router
  6. In the Select Role popup, click Core Router
  7. Then click Select

  8. Click Ok in the warning popup that informs that you must perform a Recalulate and Deploy.

Step 2 - Review ISN Router Role

Review the switch role you set. Again, each switch role will serve a purpose in the type and amount of exact configuration required to be deployed to a given switch, in this case, an external device.
