BGP basic configuration example
Network requirements
In Figure 182, run eBGP between Router A and Firewall, and run iBGP between Firewall and Router B so
that Router B can access the network 8.1.1.0/24 connected to Router A.

Configuration procedure
1. Configure IP addresses for interfaces (omitted).
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 ensure that Firewall can communicate with Router B through loopback
interfaces.
