Router1(config-if)# Advantages of per-packet load balancing Per-packet load balancing must be configured on both interface gi0/1 and gi0/0 as shown below: It must be applied to every interface that forwards traffic to the destination network that we are interested in. This command is an Interface Configuration Mode command. Per-packet load balancing can be configured using the following command: Per-packet load balancing is not the default load-balancing mode on Cisco routers. When the next packet has to be routed to 10.20.0.0/24, the router will forward it to 10.0.0.2 and the round-robin process continues. The third packet will be forwarded to 10.0.2.2. The next packet that must be routed to the network 10.20.0.0/24 will be routed over the 2nd path (10.0.0.3).

In our example, the first time that the router has to route a packet to the destination network 10.20.0.0/24 the router chooses the first route available (10.0.0.2). When a router is configured for per-packet load balancing, IP packets are distributed evenly across the available routes for a network on a per-packet basis.

When the router receives an IP packet addressed to 10.20.0.10 how does it decide where to forward that packet? Per-packet load balancing All 3 static routes are for the destination network 10.20.0.0/24. There are 2 connected routes and 3 static routes installed in the routing table.
