Jeff, VXRs and down. Not GSR's and up. I wasn't entirely clear in my last message. Like Travis I was also commenting about the Cisco GSR / 12000 platform. I'm well aware of the performance of a Linux box compared to a VXR. We run a few VXR routers in our network in addition to GSR's, BSD routers, and MikroTik.
What you're describing really isn't true hardware redundancy. I'm also well aware of BGP and its use in a multi-homed environment. We have two separate GSRs acting as our edge routers. One in California, one in Arizona. Both routers have multiple eBGP peers, and run iBGP between them. They're connected by a series of licensed microwave radios with about 155mbps of bandwidth between the two. We'll be supplementing that link with a dedicated GigE fiber link in the coming months. I'm not sure what you're getting at regarding bridging between two connections. There's no requirement to run a bridged network in order to operate iBGP. I have no doubt Quagga works well in some BGP applications. We don't use it because we have requirements for performance & uptime which a Linux/BSD box cannot currently meet. We provide voice (TDM) and data services for companies in various industries such as mining, manufacturing, aerospace, defense, energy, cellular, and even other ISPs. We literally cannot afford to wrestle with the issues others on this list experience. If its not reliable we replace it. We don't have a problem paying for reliability. -- Blake Covarrubias On Nov 3, 2010, at 1:16 PM, Jeff Broadwick - Lists wrote: > Hi Blake, > > I’m not sure what sort of speeds you think Linux limits out at, but I believe > you might be surprised at how much throughput you can get.
