The BGP Next Hop Propagation feature provides additional flexibility when designing and migrating
networks. The BGP Next Hop Propagation feature allows a route reflector to modify the next hop
attribute for a reflected route and allows Border Gateway Protocol (BGP) to send an update to an external
BGP (eBGP) multihop peer with the next hop attribute unchanged.
