I beg to differ. We had much more pain trying to get those things to
work properly than putting together two boxes that have been up now for
almost a year without incident. Running Zebra, keepalived, etc., without
any problems at all. What Zebra quirks? There has not yet been one
crash or failure, which is much better than we could say for the 7206s.
And I wouldn't exactly call it difficult to "squeeze" performance out of
a PC when the 7206 VXRs have a 200 MHz processor.
The main reason we switched is when we realized we could set up a
powerful Linux box full of gigabit NICs for less than the price of one
gigabit interface. At the time we purchased the NICs (3C996B-T) for less
than $150 CDN each, and they're probably cheaper now.
