BGP load balancing configuration
Network requirements
As shown in Figure 64, all routers run BGP, and Router A resides in AS 65008, and Router B and Router
C reside in AS 65009. EBGP runs between Router A and Router B, and between Router A and Router C.
IBGP runs between Router B and Router C. Configure two routes on Router A for load balancing.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure BGP connections:
{ On Router A, establish EBGP connections with Router B and Router C, respectively; configure
B G P t o a dv e r t i s e n e t wo r k 8 .1.1. 0 / 24 t o Ro u t e r B and Router C, so Router B and Router C can
access the internal network connected to Router A.
{ On Router B, establish an EBGP connection with Router A and an IBGP connection with Router
C; configure BGP to advertise network 9.1.1.0/24 to Router A, so Router A can access the
intranet through Router B; configure a static route to interface loopback 0 on Router C (or use a
routing protocol like OSPF) to establish the IBGP connection.
{ On Router C, establish an EBGP connection with Router A and an IBGP connection with Router
B; configure BGP to advertise network 9.1.1.0/24 to Router A, so Router A can access the
