Figure 2: Customer to Cuertomer Edge(support VRF-Lite Topology

Figure 1 is a simplified example of the connections between customer and customer edge. RIP is
the routing protocol used in VPN1 and VPN2. The example following the illustration show how
to configure a Canoga 9170/91719175 switch as Customer Switch A, B and C, and the VRF
configuration for CE Switch D.
The CE router using Mutil-VRF CE can segment its LAN traffic by placing each client or
organization with its own IP address space either on separate routed port or through separate
VLAN interfaces. Each routed port and VLAN interface contains its own IP address space to
separate each different client.
When receiving an outbound customer data packet from a directly attached interface, the CE
router then performs a route lookup in the VRF that is associated with that site. The specific VRF
is determined by the routed port or VLAN interface over which the data packet is received.
Support for multiple forwarding tables makes it easy for the CE router to provide the per-VPN
segregation of routing information before it is sent to the PE router.
