icmp redirects best practice

Is there a best practice for enabling or disabling icmp redirects?  Looks like I have redirects enabled and that caused a problem for a host server the other night.  A line went down, the 6500 sent a redirect that was not really a valid route and when the line came up, the host still cached the redirected route, causing a problem.  Are there any pro's and con's, although I'm leaning towards disabling redirects?

as always, thanks for your ideas.

Redirects are about efficiency; avoiding the need to transit an extra device.  If that's not a concern, turn if off.

 

(Of course there's the issue why the 6500 sent an invalid route redirect.)

thanks, the invalid route was actually a default route that sent traffic to our firewall and that was never going to work.  thanks again.
