Figure 59 , run EBGP between Switch A and Switch B, and run IBGP between Switch B and Switch C
so that Switch C can access the network 8.1.1.0/24 connected to Switch A.

Configuration considerations
To prevent route flapping caused by port state changes, this example uses loopback interfaces to
establish IBGP connections. Because loopback interfaces are virtual interfaces, use the peer
connect-interface command to specify the loopback interface as the source interface for establishing
