BGP configuration examples

BGP basic configuration example

Network requirements
In Figure 89, run EBGP between Switch A and Switch B and IBGP between Switch B and Switch C so that
Switch C can access the network 8.1.1.0/24 connected to Router A.

Configuration procedure
Configure IP addresses for interfaces. (Details not shown.)
1.
Configure IBGP:
2.
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 Switch B can communicate with Switch C through
loopback interfaces.
# Configure Switch B.
