RE: AW: /27 the new /24

[Jürgen Jaritsch <jj () anexia at>]

As mentioned before: even the new SUP2T from Cisco is limited to 1Mio routes ...

There are MANY other vendors with the same limitations: Juniper, Brocade, etc

And the solt equipment is not the 99USD trash from the super market at the corner ...

Which routers? DIR-300 with OpenWRT/Quagga? :)

I think all above-the-trash level routers supports >1M routes, isn't it?
