BGP Next_Hop Attribute
Unlike IGP, the Next_Hop attribute in BGP does not necessarily have to be the IP address of a peer interface. For example, in multi-hop BGP configurations, the Next_Hop can point to a different router or interface within the network.

I feel like I read somewhere that the Next_Hop can actually be the address of a router interface, not just the peer interface.

I’m pretty confident that the Next_Hop must be a valid IP address, but I can't recall if it has to be specifically the peer interface.

I remember practicing a question about BGP attributes, and I think it was stated that the Next_Hop can be different from the peer interface in some scenarios.

I think the Next_Hop attribute does need to be a peer interface IP, but I'm not entirely sure if that's always the case in BGP.
