Active/Active P2P

Hello,

If I have two 100Mbps Point to Point Circuits both terminating on the same equipment on both ends is there a way to utilize them in tandem so that I end up with 200Mbps of bandwidth?  If so what would that configuration be called?

All replies rated.  Thanks!

If you're given true end to end ethernet, you could do a port-channel on switches.

Make CEF do per-packet load balancing (i do not advocate this) across equal cost links in a routed environment.

Or just accept that you'll be able to do a 100mbps max per session and go with it.

The best answer is what trfinkenstadt said which is to create a LAG.

If the links are routed and have the same cost they should both be used anyway. One thing I did on my home router with two internet connections was to change to layer 4 port based load balancing instead of just IP (ip cef load-sharing algorithm include-ports). The result was double bandwidth when downloading with a client that supported multiple download streams. It worked pretty well.

I also had to use PBR to set a primary next hop for certain sensitive traffic like SSL but it wasn't a big deal.
