CEF Load balancing...

[Alex Rubenstein <alex () nac net>]

Question (kinda operational)..

I've been looking/asking around, but have yet been able to get the same
answer twice to the following question: How many links can you have in
parallel when using CEF load-sharing per-packet? 

Another words, we currently have a site that has four DS1s load balanced,
in parallel (terminating in the same router on each end). Can you add a
[5th|6th|7th|8th] ?

Before you answer "BUY A DS3!", this is located in a rural area that a)
really doesn't (easily) even have DS3 capabilites, and b) isn't cost
effective to have a DS3 as it is about 15 times the cost of a DS1.

Thanks for any insight!
