Jesper, 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... Scott At 12:57 AM 9/18/98 , Jesper Skriver wrote:
Hi,
How would you loadshare over many (>6) parallel E1 links. Currently we do it by connecting them directly to the Cisco's in each end, and do CEF based per-packet loadsharing, it works fine, but support a max of 6 E1's ...
I've been thinking om something similar to the Larscom inverse MUX (http://www.larscom.com/t3ft3/t3_megae.htm), but this one only support 4 E1's, then I can use multiple i-mux's and loadshare over the 8M links they provide, but it seems like a poor solution.
Yes, I do know that a E3 would be a far better choice, but our ADM (Add-Drop-Multiplexer??) at this specific location only support E1's :-(
