Yes, this is what I understand is the case. Most people I know that are talking about pushing this much traffic can use the PA-2FE and load-share, or use the POS OC3 pa. - jared On Thu, Mar 18, 1999 at 11:26:46PM +0000, Tony Bourke wrote:

This looks kinda like the right place for this issue, apologies if not:

True or False?

FEC (Fast EtherChannel) is not suibtable for router to router trunking because of the way FEC load balances

I've heard and read in various places (although nothing conclusive) that since FEC uses the last portion of a MAC address and hashs it to determine which 100 meg link a packet goes. This is to prevent packets from arriving on the other end out of order.

This would seem to suggest that FEC wouldn't work between routers or similar layouts because there is only one MAC address on either end, therefor packets would always go over the same link.

Anybody have concrete details on this issue? Does FEC actually determine load balancing this say? is ther another way to configure this?

I'm not real fond of FEC myself, and would like substantiated evidence in an argument against it.
