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.
