ip unreacheables.

Unanswered Question
Feb 26th, 2010


We want to disable icmp unreacheable message on interfaces that no one can see ip addresses when they traceroute..
On 7600 router i have applied no ip unreacheables on all interfaces, but still shown ip address when traceroute.

I have this problem too.

Have you ever studied how traceroute works?

That is, either TTL expired, or Record Route option.

Consequently, it is normal that disabling "Port Unreachable" has no effect.

Your best choice would be to engage a networking professional rather than attempting manouvers thta can hinder the network.
