Configuring Load-Balancing
In the following topology, two routers, NR304G-4W #1 and NR304G-4W #2, connect back-to-
back over two SHDSL interfaces (s0 and s1) with high-level data link control (HDLC)
encapsulation. The LAN interface is connected with a local network device (hub or switch). The
LAN interface supports either 10BaseT or 100BaseTx connection.

Equal cost routes can usually be found by using the
show ip route
-
v
command. For example,
below is the output for show ip route to a particular subnet that has multiple routes.
Example:
NR304G-4W_1(conf)# sh ip route -v
