8.27.4 Route Attributes

Next_Hop
BGP ignores routes with an unreachable next hop address during BGP route selection.
Unlike the Next_Hop attribute in an IGP, the Next_Hop attribute in BGP is not necessarily the
IP address of a neighboring device. In most cases, the Next_Hop attribute in BGP complies with
the following rules:
Issue 02 (2014-09-30)
