issued on the router interface.
When routes are not optimal on this router and another router on the same subnetwork has a better 
route, the router can issue an ICMP redirect to alert the sending node that a better route is available.
The redirects command enables the generation of ICMP redirects on the router interface. The rate at 
which ICMP redirects is issued can be controlled with the optional number and seconds parameters 
by indicating the maximum number of redirect messages that can be issued on the interface for a 
given time interval. 
By default, generation of ICMP redirect messages is enabled at a maximum rate of 100 per 10 second 
time interval.
