Aaaahhhhhh...i get it now. Right after i send my last post, i've been thinking about it. Now i know why the answer of that OEQ is THAT.. :)
Eventhough i still don't quite certain the default load-balancing type if the Etherchhannel is CONNECTED to the router. Can anybody point me out at the right direction?

Whether it's source mac or source ip. Because if we use load-balance based on destination, it will use the same link/port over and over. for the scenario from Marko, default load-balance will be based on the switch devices itself. Which port will be used first, i still can't find the reference. But we can test it out, on the Switch Processor console by emulating traffic form certain IP/MAC to other IP/MAC Sources : http://www.ciscosystems.com/en/US/tech/tk389/tk213/technologies_tech_not e09186a0080094714.shtml#cat6k Just my 2 cents.. :) Regards, Dani A. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Marko Milivojevic Sent: 06 April 2010 23:20 To: Patrice Ngassam Cc: [email protected] Subject: Re: [OSL | CCIE_RS] OEQ question 7 On Tue, Apr 6, 2010 at 16:02, Patrice Ngassam <[email protected]> wrote: > the first link to be added into the port channel.
