In external BGP (eBGP) sessions, which IP address is sent as the next hop?
A. In eBGP peering, the next hop is the IP address of the neighbor that announces the route. However, when the route is advertised on a multi-access media (such as Ethernet or Frame Relay), the next hop is usually the IP address of the router interface connected to that media, which originated the route. Refer to the BGP Next Hop Attribute of BGP Case Studies for a more detailed explanation.
