BGP load balancing configuration
Network requirements
As shown in Figure 91, 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.
a.
Configure Switch A.
