The following example shows how to send SNMP information for all VRFs to SNMP host 192.0.2.1,
reachable on VRF Red:
switch# config t
switch(config)# snmp-server host 192.0.2.1 for-all-vrfs use-vrf Red
switch(config)# copy running-config startup-config
The following example shows how to Filter SNMP information for VRF Blue to SNMP host 192.0.2.12,
reachable on VRF Red:
switch# config t
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

Command
routing-context vrf vrf-name
Example:
switch# routing-context vrf red
switch%red#
To return to the default VRF scope, use the following command in EXEC mode:
