Step 5
interface interface-type slot/port
Example:
switch(config)# interface ethernet 1/2
switch(config-if)#
Step 6
vrf member vrf-name
Example:
switch(config-if)# vrf member
RemoteOfficeVRF
Step 7
ip address ip-prefix/length
Example:
switch(config-if)# ip address
192.0.2.1/16
Step 8
ip router ospf instance-tag area area-id
Example:
switch(config-if)# ip router ospf 201
area 0
Step 9
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
This example shows how to create a VRF and add an interface to the VRF:
switch# configure terminal
switch(config)# vrf context RemoteOfficeVRF
switch(config-vrf)# exit
switch(config)# router ospf 201
switch(config-router)# vrf RemoteOfficeVRF
switch(config-router-vrf)# maximum-paths 4
switch(config-router-vrf)# interface ethernet 1/2
switch(config-if)# vrf member RemoteOfficeVRF
switch(config-if)# ip address 192.0.2.1/16
switch(config-if)# ip router ospf 201 area 0
switch(config-if)# exit
switch(config)# copy running-config startup-config

Configuring a VRF-Aware Service

You can configure a VRF-aware service for reachability and filtering. See the
section on page 9-3
to configure the service for VRFs. This section uses SNMP and IP domain lists as example services for
the detailed configuration steps.
