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:
