You know if I didn't know better, I would think this was a troll. :) Everyone's workhorses are different, depending on what kind of work you want to do with them. The 7200VXR (which is what I assume you meant) and 7301 are the last great "mostly cpu based" routers out there, which is why they have lasted as long and become as widely used as they have. Any time you have a CPU based solution it is going to be easier to add new features quickly, and handle a wide variety of tasks. Personally I couldn't find a use for either one in my network on a dare, but that is because I care about capacity not high touch services or L2TP termination. It is pretty hard to predict what box is going to be the "it" thing for the next 5 years, though I certainly agree that anyone interested in making smart purchases needs to be concerned about the viability of the product over exactly that kind of timeframe. For my needs, the Juniper M160 has been the workhorse for the past 3-5 years, though its time is rapidly coming to an end. The weapon of choice for L3 ethernet aggregation is certainly now the 6500/7600 SUP720 based platforms, and will probably see a good 5 years worth of use and deployment. Folks like Foundry, Extreme, and Force10 have all come out with interesting "nextgen" boxes at L2, but I think they've already lost the L3 war to Cisco before firing a single shot. I'm not entirely certain that the next 5 years has been ironed out in the carrier space yet. There is still plenty of opportunity for Juniper to be dethroned if they follow through with some of the disturbing trends they've been setting (and from all indications, we won't be seeing anything new or even close to revolutionary for at least 2 years). The point has been made that this pattern of becoming complacent re: innovation and cost effectiveness until you get your ass handed to you by a competetive product is the natural cycle of things, and we may very well be near another turning point in the market like what happened when Juniper first hit the scene. The CRS1 hasn't made significant headway into the market yet either though, most likely due to its lack of any low-end or "non-40Gbps" cards as an upgrade path for existing GSR users. I wouldn't be surprised to see the 7206VXR and 7301 still in use 5 years from now though, some roles just aren't that demanding traffic-wise, and are better served by a CPU based solution. I couldn't tell you if there are plans for a bigger beefier CPU-based router (not my area of concern really), but in that space I think the 7300 may be a safe bet for the near future. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
