... turns 20 today.

This is the patent which covers hsrp, vrrp, many applications of carp and
some other vendor-specific standby protocols.  Assuming no term
adjustments, 20 years is the normal term for US patents so unless there's
been any adjustments / continuations, probably this patent is now expired.
