Local Preference: Highest. Network or Aggregate: Locally originated. AS_PATH: Shortest.When set ip next-hop is used with the peer-address keyword in an inbound route map of a BGP peer, the next hop of the received matching routes will be set to be the neighbor peering address, overriding any third-party next hops.

Route leaking between Global Routing Table (GRT) and Virtual Routing and Forwarding (VRF) table is facilitated with the use of static routes.
