Configure BCBs for Inter-VSN Routing
Inter-VSN allows you to route between IP networks on Layer 2 VLANs with different I-SIDs. Inter-VSN routing is typically used only when you have to extend a VLAN as a Layer 2 Virtual Services Network (VSN) for applications such as vMotion. Use IP Shortcuts to route traffic. You must configure both the Backbone Edge Bridges (BEBs) and the Backbone Core Bridge (BCB).
Note
To enable inter-VSN routing, you must configure the IP interface where the routing instance exists.
Before you begin
-
You must configure the required SPBM and IS-IS infrastructure.
-
You must configure the BEBs that contain the VSNs you want to route traffic between. For more information, see Configure BEBs for Inter-VSN Routing.
