BGP configuration examples
BGP basic configuration
Network requirements
In Figure 73, 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 procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure IBGP:
{ 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.
# Configure Router B.
