I would have thought that this lesson would still be fresh in the
minds of people, as we just passed 256K routes a little while ago
and broke a whole bunch of Catalyst 6500/7600 SUP720-3B's (etc).
I guess the pain isn't as memorable as I thought.
Not all of us forgot... I remember the day

Looking at two 100Mbit/s BGP connections, so I think I want something that will
do more than 100 but nowhere close to a gig. So full routing table capability
with throughput of mixed traffic around 200Mbit/s. If that makes sense. Do
the 2850s fall into that sort of price point?

Their offering certainly looks appealing. Will be interested to hear user

Most purpose-built routing appliances use ternary content
addressable memory (TCAM) in order to accomplish deterministic,
hardware-based, longest-prefix lookups in large routing tables,
such as a full Internet BGP feed. TCAM is used to replace
software-based table lookup algorithms which

I think partial routes makes perfect sense, makes sense that traffic for
customers who are connected to each of my upstreams should go out of
the correct BGP link as long as they are up! Now I need to start thinking of
