Personally (and as the instigator in the ipv6/6man discussion) if the vendors could be trusted to expose their default settings in their configs, i would find a default of ON to be more acceptable. As their track-record is poor, and the harm has been realized in the network we operate (at least), I am advocating that as a matter of policy enabling redirects not be a default-on policy. If people want to hang themselves that's their problem, but at least they won't come with a hidden noose around their neck.
On Cisco routers (at least some of them), have you tried the command show running-config all This command displays all configuration, including hidden default values. This may help when this command is present. Don't know about other vendors. Yann
