This parameter allows the user to configure the
time period which unreachable routes will be held in
the Routing Pool. This time is typically 3 x the broadcast
timer. It allows RIP to advertise the unreachable routes
to help convergence time. If DOR ( Dial Optimized Routing )
is configured the default value would be 1209600 two weeks
, and maximum value of 3628800 ( 6 weeks ).
