Tuning routing table size in FreeBSD 8.0 and 7.2

Sysctl -a lists "all" options.  This MAY be what you want:

net.inet.ip.rtmaxcache
 - Upper limit on dynamically learned routes

Hi,
Could you plz share the information on the maximum number of routes that can
be added (by default) in FREEBSD 8.0/7.2 kernel?
In Linux the sysctl rt_max_size is used. Is there a similar tunable
parameter in freeBSD?

Your earliest reply in this regard is much appreciated.

Thanks for any inputs..
