Chapter 11 Configuring Layer 3 Virtualization
Configuring VRFs
This example shows how to send SNMP information for all VRFs to SNMP host 192.0.2.1, reachable on
VRF Red:
switch# configure terminal
switch(config)# snmp-server host 192.0.2.1 for-all-vrfs use-vrf Red
switch(config)# copy running-config startup-config
This example shows how to Filter SNMP information for VRF Blue to SNMP host 192.0.2.12, reachable
on VRF Red:
switch# configure terminal
switch(config)# vrf definition Blue
switch(config-vrf)# snmp-server host 192.0.2.12 use-vrf Red
switch(config)# copy running-config startup-config
Setting the VRF Scope
You can set the VRF scope for all EXEC commands (for example, show commands). This automatically
restricts the scope of the output of EXEC commands to the configured VRF. You can override this scope
by using the VRF keywords available for some EXEC commands.
To set the VRF scope, use the following command in EXEC mode:
To return to the default VRF scope, use the following command in EXEC mode:
Step 4
ip domain-list domain-name
[all-vrfs][use-vrf vrf-name]
Example:
switch(config-vrf)# ip domain-list List
all-vrfs use-vrf Blue
switch(config-vrf)#
Configures the domain list in the VRF and optionally
configures the VRF that Cisco NX-OS uses to reach
the domain name listed.
Step 5
copy running-config startup-config
Example:
switch(config)# copy running-config
startup-config
(Optional) Saves this configuration change.
