Use the no ip vrf vrf-name global configuration command to delete a VRF and to remove all interfaces
from it. Use the no ip vrf forwarding interface configuration command to remove an interface from the
VRF.

Configuring VRF-Aware Services

IP services can be configured on global interfaces, and these services run within the global routing
instance. IP services are enhanced to run on multiple routing instances; they are VRF-aware. Any
configured VRF in the system can be specified for a VRF-aware service.
VRF-Aware services are implemented in platform-independent modules. VRF means multiple routing
instances in Cisco IOS. Each platform has its own limit on the number of VRFs it supports.
VRF-aware services have the following characteristics:
•
•
These services are VRF-Aware:
•
•
•
•
•
•
•
Note VRF-Aware services are not supported for Unicast Reverse Path Forwarding (uRPF).

The user can ping a host in a user-specified VRF.
ARP entries are learned in separate VRFs. The user can display Address Resolution Protocol (ARP)
entries for specific VRFs.
ARP
Ping
Simple Network Management Protocol (SNMP)
Hot Standby Router Protocol (HSRP)
Syslog
Traceroute
FTP and TFTP
Purpose
Create a list of import, export, or import and export route target
communities for the specified VRF. Enter either an AS system number
and an arbitrary number (xxx:y) or an IP address and an arbitrary
number (A.B.C.D:y). The route-target-ext-community should be the
same as the route-distinguisher entered in Step 4.
(Optional) Associate a route map with the VRF.
Specify the Layer 3 interface to be associated with the VRF, and enter
interface configuration mode. The interface can be a routed port or SVI.
Associate the VRF with the Layer 3 interface.
Return to privileged EXEC mode.
Verify the configuration. Display information about the configured
VRFs.
(Optional) Save your entries in the configuration file.
