Configuration considerations
On Switch A:
•
Establish EBGP connections with Switch B and Switch C.
•
Configure BGP to advertise network 8.1.1.0/24 to Switch B and Switch C, so that Switch B and
Switch C can access the internal network connected to Switch A.
On Switch B:
•
Establish an EBGP connection with Switch A and an IBGP connection with Switch C.
•
Configure BGP to advertise network 9.1.1.0/24 to Switch A, so that Switch A can access the
intranet through Switch B.
•
Configure a static route to interface loopback 0 on Switch C (or use a routing protocol like OSPF)
to establish the IBGP connection.
On Switch C:
•
Establish an EBGP connection with Switch A and an IBGP connection with Switch B.
