Network requirements
In Figure 284, run EBGP between Firewall A and Firewall B and IBGP between Firewall B and Firewall
C so that Firewall C can access the network 8.1.1.0/24 connected to Firewall 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 Firewall B can communicate with Firewall C
through loopback interfaces.
# Configure Firewall B.
