this is a little bit vague for us to assist you.
Is it for a lab or a production network ?
What type of traffic do you want to loadbalance ?
Do you just want to do firewall loadbalancing ?
Are the routers used as firewall ?
Do you have MSFC on the catalyst ?
How many VLAN do you have ?
Where are the servers located ?
Where are the users located ?
Do you have a connection to the internet ?
Please be more specific.
Gilles.
