Chapter 38 Configuring IP Unicast Routing
Configuring Multi-VRF CE
Use the no router bgp autonomous-system-number global configuration command to delete the BGP
routing process. Use the command with keywords to delete routing characteristics.
Multi-VRF CE Configuration Example
Figure 38-7 is a simplified example of the physical connections in a network similar to that in
Figure 38-6. OSPF is the protocol used in VPN1, VPN2, and the global network. BGP is used in the CE
to PE connections. The examples following the illustration show how to configure a 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.
