BGP load balancing configuration
Network requirements
As shown in
, all the switches run BGP. Switch A resides in AS 65008, Switch B and Switch C
in AS 65009. Between Switch A and Switch B, Switch A and Switch C are eBGP connections, and
between Switch B and Switch C is an iBGP connection. Two routes are configured on Switch A for load
balancing.

Configuration procedure
1.
Configure IP addresses for interfaces. (Details not shown)
2.
Configure BGP connections.
•
On Switch A, establish eBGP connections with Switch B and Switch C respectively; 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;
configure BGP to advertise network 9.1.1.0/24 to Switch A, so that Switch A can access the intranet
through Switch C; configure a static route to interface loopback 0 on Switch B (or use another
protocol like OSPF) to establish the iBGP connection.
