I'm wondering if any of you are familiar with a Cisco product that provides outbound load balancing over several links w/o using BGP.
Basically, Cisco's equivalent to:
- Linksys RV082:
I figure that, since a Cisco-based Linksys device offers this, there must be a more enterprise Cisco product offering it, too, but the Cisco reps I've talked to haven't been very helpful.
Thanks,
Just configure multiple default routes, and it will load share over all of them.
That's not what the Cisco SE's have been telling me. They're suggesting using CEF on top of multiple default routes to get any type of load balancing. It's apparently not as robust as other solutions by SonicWall / FatPipe/ F5, but it seems to be Cisco's answer right now.
Anyone ever used CEF?
You need to use CEF if you want per-packet load balancing without excess overhead. If you don't enable CEF, the default is per-destination load balancing, unless you turn off the route-cache, but that can have serious performance impact.
What about getting per connection load balancing (with TCP, not UDP obviously)?
That's the approach I've seem implemented on alternative products. Based on what the Cisco SE said, CIOS only has per destination or per packet load balancing, but no round robin per connection load balancing.
Thanks.
IIRC, one of the options with CEF is per-flow load balancing.
That would be nice, but I don't see it. Per-packet or per-destination are the only types that it seems to support unless I'm missing something obvious.
