Hi Darth,
I dont know whether I get you right or not, but I would say any Cisco
router
with modern IOS should be able to do that.
It's typically a combination of IP SLA, object tracking, policy NATing,
and
policy routing.
You accomplish load-balancing by using PBR to send out different groups
of
sources out different internet links, while tracking the state of each
link
so you can failover onto another link which you specify to be secondary
for
that source group.
The document below may prove useful
http://www.cisco.com/en/US/tech/tk364/technologies_configuration_example
09186a0080211f5c.shtml
However, it's a very simple configuration example. It gets more complex
if
you have to do NAT on the router, in which case you need to use policy
NATing.
Let me know if this isnt very clear. I could get provide more details.
In short, use IP SLA to keep uptime statistics on the links, Object
Tracking
to track the IP SLA objects, PBR to load balance traffic based on the
source, and the 'next-hop verify-reachability' feature to help fail over
to
the other links if one goes off.
Regards,
Felix
