The configuration for router C1 (a Cisco router) is as follows:
The configuration for router C2 (a Cisco router) is as follows:
EBGP Multihop Configuration Example
EBGP Multihop refers to a configuration where external BGP neighbors are not connected
to the same subnet. Such neighbors are logically, but not physically connected. For
example, BGP can be run between external neighbors across non-BGP routers. Some
additional configuration is required to indicate that the external peers are not physically
attached.
