The feature adds support for dynamic prefix-list to match on all protocol routes, and not just BGP. Dynamic prefix-list policy construct is similar to the traditional IP and IPv6 prefix-list, except that they have an additional state associated. This state associated with the dynamic prefix-lists, is determined on the basis of the route entries in FIB, and hence as and when the FIB changes, the state also changes dynamically.
