Configure SPBM IPv6 Layer 3 VSN using CLI
Before you begin
-
You must enable IPv6 Shortcuts.
-
You must configure the required SPBM IS-IS infrastructure.
-
You must configure a VRF instance on the switch. For more information, see VRF Lite Configuration using CLI.
About this task
After you have configured the SPBM infrastructure, you can enable SPBM Layer 3 VSN to advertise IPv6 routes across the SPBM network using the following procedure.
Procedure
Examples
Create the IPv6 VPN instance:
