Maybe not full routing dualstack but it will at least last longer than a MLX. So if you HAVE to buy a platform today why not buy one that last one or two more years ? for approx 20% more of the price. <br><br>// Andreas<br>

</div>Not exactly "ample". XMR has room for 1,000,000 routes in hardware.<br>
That is room for 170,000 v6 routes on top of the current 320,000 v4<br>
routes. Those will blow up, too. I am guessing that the breaking<br>
point will be somewhere around 400,000 v4 routes and 100,000 v6<br>
routes. The price difference between MLX and MXR blades is pretty<br>
steep for no other benefit than more routes. First vendor to get to<br>
market with a huge CAM resource is going to win, bigtime. I don't<br>
believe any hardware currently built for the medium size market will<br>
handle full routes dual-stacked once v6 is the norm.<br>
