Hi, Maybe if you could post parts of your config file I can compare with our config file. It almost sounds like you are missing the static routes out both interfaces (unnumbered). Here is what we have on our Cisco going to a customer: ip route 69.20.190.12 255.255.255.252 ATM1/0.551 69.20.190.6 ip route 69.20.190.12 255.255.255.252 ATM1/0.641 69.20.190.10 So we route the 69.20.190.12/30 network to both interfaces AND both IP's on the remote side. This was a critical thing that took us a while to figure out. Travis Microserv RickG wrote: I'm glad this subject has come up! I've got two ATT T1's. At their request, we run Cisco CEF with per-packet load balancing. I am able to get 2.8Mbps down but the upload is rarely above 1.5Mbps, sometime 1.8Mbps. I measure this with my laptop plugged directly into our Cisco 7204 VXR router using a multitude of speed test sites, running multiple times. ATT says they see no issues. Any thoughts? -RickGOn Sat, Jan 24, 2009 at 12:01 PM, Travis Johnson <t...@ida.net> wrote:Hi, That's not good news... when we use Cisco CEF and per-packet load balancing, we get the full speed. We currently have a customer that has 4 bonded 4Mbps DSL lines, and they get 16Mbps any time they run a speed test. And, now that I think about it, at one of our very remote POP's, we have two T1 lines from Verizon using MLPPP and we get a full 3Mbps. We are using an Imagestream router at this location... I'm not sure what Verizon is using. Travis Microserv Adam Greene wrote: Yep, we're bonding DSL with MLPPP as well, with direct PVCs through Verizon. Caveat: we generally see only about 80% performance rates (i.e. if [4] 1Mbps circuits are bonded together, we get 3.2Mbps throughput). Have not found a way to improve this. Using Cisco gear on both ends. ----- Original Message ----- From: "Jeff Broadwick" <jeffl...@comcast.net> To: <e...@wisp-router.com>; "'WISPA General List'" <wireless@wispa.org> Sent: Friday, January 23, 2009 5:32 PM Subject: Re: [WISPA] bonding Hi Eje, Yes, you are correct.

We are a "megahost" provider, meaning we have a DS3 directly to Qwest, and then we can sell DSL circuits using our bandwidth, etc. In the past, we have been able to "bond" multiple DSL lines using a Cisco router on the customer side and then using Cisco's CEF protocol. This provides a true bonded connection, because it does a "per packet" load balance. Is there a better solution? I have to use a Cisco on our NOC side, but I would prefer to find something cheaper. Any ideas on what protocol may work? MLPPP or ????? Travis Microserv ---------------------------------------------------------------------------- ---- WISPA Wants You!
