IPv4 BGP configuration examples
Basic BGP configuration example
Network requirements
In Figure 62, run EBGP between Router A and Router B, and run IBGP between Router B and Router C so
that Router C can access the network 8.1.1.0/24 connected to Router 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, you need to use the peer
connect-interface command to specify the loopback interface as the source interface for establishing
BGP connections. Enable OSPF in AS 65009 to make sure that Router B can communicate with Router
C through loopback interfaces.
