Chapter 14 Configuring Layer 3 Virtualization
Configuring VRFs
2. vrf context vrf-name
3. configure optional parameters
4. show vrf [vrf-name]
5. copy running-config startup-config
DETAILED STEPS
Use the no vrf context command to delete the VRF and the associated configuration:
Any commands available in global configuration mode are also available in VRF configuration mode.
The following example shows how to create a VRF and add a static route to the VRF:
switch# config t
switch(config)# vrf context Enterprise
switch(config-vrf)# ip route 192.0.2.0/8 192.0.2.10
switch(config-vrf)# exit
switch(config)# copy running-config startup-config
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Enters configuration mode.
Step 2
vrf context name
Example:
switch(config)# vrf definition
Enterprise
switch(config-vrf)#
Creates a new VRF and enters VRF configuration
mode. The name can be any case-sensitive
alphanumeric string up to 32 characters.
Step 3
ip route { ip-prefix | ip-addr ip-mask }
{[
next-hop | nh-prefix ] | [ interface
next-hop
| nh-prefix ]} [tag t ag-value
[
pref ]
Example:
switch(config-vrf)# ip route 192.0.2.0/8
ethernet 1/2 192.0.2.4
Configures a static route and the interface for this
static route. You can optionally configure the next-hop
address. The preference value sets the administrative
distance. The range is from 1 to 255. The default is 1.
Step 4
show vrf [ vrf-name ]
Example:
switch(config-vrf)# show vrf Enterprise
(Optional) Displays VRF information.
Step 5
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
(Optional) Saves this configuration change.
Command Purpose
no vrf context name
Example:
switch(config)# no vrf context Enterprise
Deletes the VRF and all associated configuration.
