If set to false for a directly connected eBGP peer, routes received from the peer with a next-hop that is not the peer's remote address and is not in a subnet shared with the remote device will be rejected, in accordance with RFC 4271 section 6.3. If set to true, this check is not performed, and such routes may be accepted. This is useful when communicating with an eBGP peer that preserves the next-hop of routes that it advertises. The peer may be configured to ignore this field and instead obtain the value from a peer-group as explained in the table description.
