Parameters
update Enter the number of seconds to specify the rate at which RIP routing updates are
sent. The range is from zero (0) to 4294967295. The default is 30 seconds.
invalid Enter the number of seconds to specify the time interval before routing updates
are declared invalid or expired. The invalid value should be at least three times the
update timer value. The range is from zero (0) to 4294967295. The default is 180
seconds.
holddown Enter the number of seconds to specify a time interval during which the route is
marked as unreachable but still sending RIP packets. The holddown value should be
at least three times the update timer value. The range is from zero (0) to
4294967295. The default is 180 seconds.
flush Enter the number of seconds to specify the time interval during which the route is
advertised as unreachable. When this interval expires, the route is flushed from the
routing table. The flush value should be greater than the update value. The range is
from zero (0) to 4294967295. The default is 240 seconds.
