Re: Why can not use both ICMP Redirect and HSRP ?

According to RFC 2281:"
While running HSRP, it is important to prevent the host from
   discovering the primary MAC addresses of the routers in its standby
   group. Thus, any protocol that informs a host of a router's primary
   address should be disabled. Thus, routers participating in HSRP on
   an interface MUST NOT send ICMP redirects on that interface."

If I simply do a ping from the host to the ip address on the interface(not
the HSRP address), the the host will learn the primary MAC address of the
interface anyway, right?
I am trying to figure out what is going to happen if I enable icmp redirect
on the interface running HSRP?
