I operate freebsd / quagga core routers since 4 years.
pro: cheap, tcpdump at router
con: no support, no wirespeed
expected performance: 100kpps (1,2ghz pentium m) - 700kpps (quad intel
core 2, 3ghz) - and much more with 10gige cards
issues: 4byte asn produced a crash at quagga (downtime 2h in 4 years)
to develop a good core-router, this means not only to setup a pc with unix
and for example quagga, but setup an embedded unix to an appliance, for
example with cf-cards (readonly).
