Switch A and B have established an eBGP connection; Switch B, C, and D have established iBGP
connections with each other.
IPv6 BGP route reflector configuration
Network requirements
As shown in the following figure, Switch B receives an eBGP update and sends it to Switch C, which is
configured as a route reflector with two clients: Switch B and Switch D.
Switch B and Switch D do not need to establish an iBGP connection because Switch C reflects updates
between them.
