to PE connections. The examples following the illustration show how to configure a Catalyst 3750 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. The example also
includes commands for configuring traffic to Switch A for a Catalyst 6000 or Catalyst 6500 switch acting
as a PE router.
