Chapter 38 Configuring IP Unicast Routing
Configuring Multi-VRF CE
• Multi-VRF CE does not affect the packet switching rate.
• VPN multicast is not supported.
• You can configure 104 policies whether or not VRFs are configured on the switch or the switch
stack.
• You can enable VRF on a private VLAN and the reverse.
• You cannot enable VRF when policy-based routing (PBR) is enabled on an interface and the reverse.
• You cannot enable VRF when Web Cache Communication Protocol (WCCP) is enabled on an
interface and the reverse.
Configuring VRFs
Beginning in privileged EXEC mode, follow these steps to configure one or more VRFs. For complete
syntax and usage information for the commands, see the switch command reference for this release and
the Cisco IOS Switching Services Command Reference, Release 12.2.
Use the no ip vrf vrf-name global configuration command to delete a VRF and to remove all interfaces
from it. Use the no ip vrf forwarding interface configuration command to remove a specific interface
from the VRF.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 ip routing Enable IP routing.
Step 3 ip vrf vrf-name Name the VRF, and enter VRF configuration mode.
Step 4 rd route-distinguisher Create a VRF table by specifying a route distinguisher.
Enter either an autonomous-system number and an
arbitrary number (nnn:y) or an IP address and arbitrary
number (A.B.C.D:y)
Step 5 route-target {export | import | both}
route-target-ext-community Create a list of import, export, or import and export
route-target communities for the specified VRF. Enter
either an autonomous-system number and an arbitrary
number (nnn:y) or an IP address and an arbitrary number
(A.B.C.D:y). The route-target-ext-community should be
the same as the route-distinguisher entered in Step 4.
Step 6 import map route-map (Optional) Associate a route map with the VRF.
Step 7 interface interface-id Specify the Layer 3 interface to associate with the VRF,
and enter interface configuration mode. The interface can
be a routed port or an SVI.
Step 8 ip vrf forwarding vrf-name Associate the VRF with the Layer 3 interface.
Step 9 end Return to privileged EXEC mode.
Step 10 show ip vrf [brief | detail | interfaces]
[vrf-name] Verify the configuration. Display information about the
configured VRFs.
Step 11 copy running-config startup-config (Optional) Save your entries in the configuration file.
