Re: Load Balancing... [7:14865]
Be prepared to take a SERIOUS cpu hit if you do per packet load balancing like that. I personally would do LFI setup with multilink PPP instead. See link and look at the config. http://www.cisco.com/warp/public/788/voice-qos/voip-mlppp.html#subfirstone Tony M. #6172 - Original Message - From: Santosh Koshy To: Sent: Saturday, August 04, 2001 5:06 PM Subject: Re: Load Balancing...

RE: Load Balancing... [7:14865]
Since you're concerned about redundancy, have you verified that the two providers you have selected are using different physical media to transport your data to the US? Fiber seems to be grossly incestuous up here with telcos leasing bandwidth to other telcos. The redundancy you think you're getting may not be as redundant as you think. Something else to check on in your quest for a solution... -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Santosh Koshy Sent: Saturday, August 04, 2001 6:07 PM To: [EMAIL PROTECTED] Subject: Re: Load Balancing...

Re: Load Balancing... [7:14865]
You could also, I suppose, make use of Multilink Multichassis PPP. But that is almost certainly overkill. Chuck Larrieu wrote in message news:[EMAIL PROTECTED]... yes. well, let me qualify that by saying you could terminate on four routers, and then have those four connect to a single router further upstream, which would per packet load share to each of those four routers. or on two routers, and so on. eventually, there has to be one source router that shows four equal cost routes, and load shares accordingly.
