It's a software router so the short answer is "it isn't"
With 3GB of RAM both a 4350 and 6350 can easily handle multiple IPv4
feeds and an IPv6 feed (3GB just happens to be what I have due to
upgrading from 1GB by adding a pair of 1GB sticks)
If you need more then ~500Mbit or so then you would want something
bigger. The MX80 is nice and has some cheap bundles at the moment; it's
specced for 8M routes (unspecified, but the way Juniper chips typically
store routes there's less difference in size then the straight 4x)
>From others the Cisco ASR1k or Brocade NetIron XMR (2M routes IIRC) are
the obvious choices.
