FIGURE 40 Multi-VRF topology example
This topology is a network owned by an enterprise. Normal corporate traffic must pass through the
firewall so that company policy can be enforced. However, a secondary Internet connection has been
added to this network: an unrestricted internet access designated for guests visiting the corporate
campus. The 172.16.0.0/16 network is used for Corporate traffic, and 192.168.0.0/16 is used for Guest
traffic.
All router interfaces which provide transport for both types of traffic have been configured with two
virtual interface (ve), ve X0 (VRF Guest) and ve X1 (VRF Corporate). OSPF is the routing protocol.
Step 1: System-max configuration
The default system max value must be configured because it does not have routing table space for
user VRF.
