This feature adds support to interface traffic policies for routing matched unicast IPv4 or IPv6 traffic which ingresses on L3 interfaces according to the routing table of a secondary VRF.

VRF redirection often requires matching packets’ source addresses against one or more sets of IP prefixes.  This can become difficult to manage when the prefix sets need to be consistently maintained on several devices and either change too frequently or are very large.  When the prefixes for the prefix sets are learned by BGP, this feature provides an alternative to maintaining unwieldy sets of statically configured IP prefixes.
