Re: How to loadshare over many E1 links

You might consider MLP (multi-link PPP), with VIP2/50's.
If you do go with an IMUX, I definitely recommend a HSSI to the routers, rather than Ethernet, unless the Ethernet is full-duplex. I've seen really poor performance due to collisions on the Ethernets at either end because the middle is actually 16Mbps full-duplex...
