Example for RIP: Load Balancing

• If multiple paths exist to a particular destination, RIP will load balance between those paths (by default, up to 4) only if the metric (hop count) is equal

Example for RIP: Load Balancing

R1:

R1(config-if)#router rip
R1(config-router)#network 10.0.0.0
R1(config-router)#network 20.0.0.0
R1(config-router)#network 30.0.0.0

R2:

R2(config-if)#router rip
R2(config-router)#network 20.0.0.0
R2(config-router)#network 40.0.0.0

R3:

R3(config)#router rip
R3(config-router)#network 30.0.0.0
R3(config-router)#network 50.0.0.0

R4:

R4(config-if)#router rip
R4(config-router)#network 40.0.0.0
R4(config-router)#network 50.0.0.0
R4(config-router)#network 60.0.0.0

R1:

R1: IP Route

Here, hop count is 2 (i.e. via 20.0.0.2 and 30.0.0.2), to reach the destination 60.0.0.0.

So if I want to reach PC2 (60.0.0.10) from PC1 (10.0.0.10), RIP will work as a load balance to reach destination 60.0.0.10 in R1.
