Whether or not the local BGP speaker should override the use of third party next hop by an EBGP peer. If an EBGP peer speaker uses third party next hop, routes learnt from the peer may specify a next hop belonging to a router that the local BGP speaker does not peer with. If this field is set to 'true', then all data forwarded along a route learnt from an EBGP peer will be sent to the EBGP peer. The peer's address is put into the BGP next hop field when the route is advertised to IBGP peers. If set to 'false', then data is sent to the next hop specified by the peer. The field is only used when importing routes from EBGP.
