Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Copyright Notice Copyright (C) The Internet Society (2000). Abstract This document defines a new Border Gateway Protocol (BGP) capability termed 'Route Refresh Capability', which would allow the dynamic exchange of route refresh request between BGP speakers and subsequent re-advertisement of the respective Adj-RIB-Out.

One possible application of this capability is to facilitate non-disruptive routing policy changes.

Instead of a route-map like IOS, IOS XR uses a Route Policy Language (RPL) – that is more powerful and easier than IOS.
