In the following network, 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.

2) Configure 

iBGP 

z 

To prevent route flapping caused by port state changes, this example uses loopback interfaces to 

establish iBGP connections.  

z 

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.  

z 

Enable OSPF in AS 65009 to ensure that Switch B can communicate with Switch C through 

loopback interfaces. 

# Configure Switch B.
