[nsp] cisco load balancing

[Arie.Gerszt@student.unisg.ch]

Hi List

Radware makes a product called Linkproof. It basically does load balancing
and automagical failover
for multiple isp's for outgoing connection. it states it using something as
smart nat. without the use
of any (i/eBGP)

as i understand it basically nat's traffic in a way that load is balanced
and in the case of a fail of one
link it just uses the other one the full extent.

What I was wondering is, if I can accomplish the same behavior with a
multiple ethernet router, say a 2621
with 3 FE for example.

basically I'd like to:

                      +--------- ISP 1 (static)
                      |
              /--------\
[firewall]----| CISCO  |
              \--------/
                      +--------- ISP 2 (static)

without using any BGP. Any suggestion of you "gurus"? :)

Thank you in advance
