This enables or disables Triple DES encryption on this specific route. This requires the 3xDES feature be licensed on the unit via cdmipEncryptionOption, again failing the set with 'commit_failed' if it is not, and works together with cdmipIpRouteDesKey, which selects which of the eight stored keys this route actually uses once encryption is enabled here. Enabling this on a route without first setting a meaningful key via cdmipIpRouteDesKey would leave the route encrypting with whatever default or unconfigured key value happens to be in that key slot, a configuration mistake worth checking for.
