We're using the Stratacom MGX8220 - We can aggregate more than 8 with multiple cards...

This is a problem because igp issues:

nnn-7202(config)#router ospf 1 nnn-7202(config-router)#maximum-paths ? <1-6> Number of paths

Because of this, you are unable to hanle those multiple paths past 6.

You also have the same isues with isis: nnn-7202(config)#router isis home1 nnn-7202(config-router)#maximum-paths ? <1-6> Number of paths

I don't have a pdf viewer (on this machine), so can't cite this right now, but I think that the dl imux will handle up to 8 E1's:

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 :-(
