Usage Guidelines
You can configure the standby redirects command globally or on a per-interface basis. When you first
configure HSRP on an interface, the setting for that interface inherits the global value. If you explicitly
disable the filtering of ICMP redirects on an interface, then the global command cannot reenable this
functionality.
