We will change the spec as noted in the comment.

We will revise the spec to make implementation of RFC 3118 mandatory.

The following text is proposed for insertion at the end of section 2.4:

"If IKE/IPSec is disabled, this indicates that the Internet Key Exchange
(IKE) Protocol is not available to configure IPSec keys for iSNS sessions to
this iSNS server.  It does not necessarily preclude other key exchange
methods (e.g., manual keying) from establishing an IPSec security
association for the iSNS session."

If IKE/IPsec is enabled, only one of Main Mode or Aggressive Mode SHALL be
enabled.  Similarly, only one of Transport Mode or Tunnel Mode SHALL be
enabled.

The following replacement text is proposed for this section:

"IANA is requested to assign a number for this option is accordance with the
policy defined in [DHCP].

"New values for other numeric and bit fields in this document SHALL only be
defined in an RFC which supercedes this specification."
