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:
•
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.
