Hi, i would like to inquire what commands should i look for in our router to know if we have load balancing? i am not familiar with the configuration and just about to read in cisco - basic load balancing page would be appreciated

The (Sh ip route x.x.x.x) should show you if there is multiple paths for a particular destination.

Hello Eduard,
generally speaking load-balancing is enabled on Cisco routers and multilayer switches but to really happen multiple static routes or dynamic routes have to be installed.
so the first step is:
sh ip route
if there are multiple equal cost paths available and used you may be interested in what link is used to foward packets of a specific flow
A useful command for this is:
show ip cef exact-route
load-balacing can be : flow based (source IP and destination IP of the packet are used to decide the outgoing path) or can be per packet.
to see what type of load-balancing is occurring you can use:
show ip interface type x/y
or show run interface type x/y
note:
Only EIGRP is able with a specific configuration to support weighted load balancing over unequal cost links
Hope to help
