configuring to not accept redirects

Is there a command similar to "no ip redirects" but in reverse? I think my router is being affected by another router sending redirects to it. I would like to configure my router to ignore these redirects.

Thanks,

Diego

Re: configuring to not accept redirects

If you keyed in the sample exactly then you forgot about the implied deny any any at the end. You need to put in a permit ip any any as the last line of the access list.

Hi,

you can block all redirects through an ACL:

access-list 100 deny icmp any host 10.1.1.1 redirect

interface FastEthernet0/0

ip address 10.1.1.1 255.255.255.0

ip access-group 100 in

Hope this helps! Please rate all posts.

Wow, that was interesting. I created and applied the ACL and it prevented all clients on the interface it was applied to from talking to anything accross the router. The weird part is that there were no hits, zero, zilch on the ACL!

How can that happen?

Thanks,

Diego

Uh... I'm an idiot.

Thanks, that was it.
