Associating a VLAN or port with a VRF instance

You can assign a VRF instance to a port or VLAN. You cannot associate a VLAN or port and a VRF instance if the VLAN or port has an IP address. You can configure the IP address after you associate the port and VRF instance.

Before you begin

Ensure the VRF is already configured.

Procedure

Enter Interface Configuration mode:

enable

configure terminal

interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} or interface vlan <1–4059>

Note

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
Associate the port or VLAN with a VRF instance:

vrf WORD<1-16>

Example

Switch:1> enable
Switch:1# configure terminal

Create a VRF named Two:

Switch:1(config-if)# ip vrf Two

Create a VLAN of type byport:

Switch:1(config-if)# vlan create 33 name vlan-30 type port-mstprstp 0

Enter VLAN Interface Configuration mode:

Switch:1(config-if)# interface vlan 33

Assign the VLAN to VRF Two:

Switch:1(config-if)# vrf Two

Give the VLAN an IP address:

Switch:1(config-if)# ip address 192.0.2.1 255.255.255.0

Enter VRF configuration mode:

Switch:1(config-if)# router vrf Two
