Multi-VRF CE Configuration Example

CE-to-PE connections. The examples following the illustration show how to configure a Catalyst 3750

Metro switch as CE Switch A and the VRF configuration for customer switches D and F. Commands for

configuring CE Switch C and the other customer switches are not included, but would be similar to those

shown. The example also includes commands for configuring traffic to Switch A for a Catalyst 6000 or

Catalyst 6500 switch acting as PE router.
