Because the BGP next-hop associated with 130.130.0.0/24 is 10.0.2.5. BGP has to resolve the next-hop for that route, which as you pointed out is the IS-IS route. This begs the question, how does IS-IS get to 10.0.2.5 and that is via the interface routes 10.0.4.9 and ...When I use show ip bgp command on R4, I can see that the path to 2.2.2.2 is valid and best.

The table is cleared after all route policies are processed.
Jun 8, 2023 · BGP Next Hop Attribute. BGP Next Hop Attribute. The BGP next hop attribute is the next hop IP address to use in order to reach a certain destination.
