Yes.

How about:

The details of IKE key exchange and other details of the IPsec security
associations between routers ->
The details of the security associations between routers

&gt; &gt;
&gt; &gt;&gt;&gt;For example, Section 6.2 talks about using of IKE to dynamically
&gt; &gt;
&gt; &gt; negotiate
&gt; &gt;
&gt; &gt;&gt;&gt;keys for protection of Inter-Router traffic.  However, it doesn't say
&gt; &gt;
&gt; &gt; what
&gt; &gt;
&gt; &gt;&gt;&gt;IKE modes need to be implemented, or what IPsec ciphersuites are
&gt; &gt;
&gt; &gt; required.
&gt; &gt;
&gt; &gt;&gt;this doesnt make a lot of sense to me.
&gt; &gt;&gt;
&gt; &gt;&gt;we can only say that there must be confidentiality protection
&gt; &gt;&gt;for the secure channel between the access routers. we also say
&gt; &gt;&gt;ESP in transport mode must be used. we also say a non-null
&gt; &gt;&gt;encryption algorithm is to be used.
&gt; &gt;&gt;
&gt; &gt;&gt;implementations have to follow IPsec specifications.
&gt; &gt;&gt;
&gt; &gt;&gt;
&gt; &gt;
&gt; &gt;
<a  href="http://www.ietf.org/internet-drafts/draft-ietf-ipsec-ikev2-algorithms-05.txt";>http://www.ietf.org/internet-drafts/draft-ietf-ipsec-ikev2-algorithms-05.txt</a>
&gt; &gt;
&gt; &gt;&gt;specifies what algorithms to use with IKE.
&gt; &gt;&gt;
&gt; &gt;&gt;<a  href="http://www.ietf.org/internet-drafts/draft-ietf-ipsec-ui-suites-06.txt";>http://www.ietf.org/internet-drafts/draft-ietf-ipsec-ui-suites-06.txt</a>
&gt; &gt;&gt;specifies what cryptographic suites to use with IPsec.
&gt; &gt;&gt;
&gt; &gt;&gt;CTP actually doesnt care which cipher suites or algorithms from
&gt; &gt;&gt;the above two drafts are used as long as the requirements for
&gt; &gt;&gt;non-null encryption algorithm, authentication, and confidentiality
&gt; &gt;&gt;protection is achieved.
&gt; &gt;&gt;
&gt; &gt;&gt;
&gt; &gt;&gt;&gt;Since context transfer security is an n by n problem, establishing the
&gt; &gt;
&gt; &gt; SAs
&gt; &gt;
&gt; &gt;&gt;&gt;to protect inter-router transfers is not an easy thing.  For this reaso
n
&gt; &gt;
&gt; &gt; one
&gt; &gt;
&gt; &gt;&gt;&gt;might conclude that pre-shared keys are difficult, since n(n-1) of them
&gt; &gt;&gt;&gt;would be necessary.  On the other hand, is it being suggested that each
&gt; &gt;&gt;&gt;router needs to be provisioned with a certificate? On reading the draft
&gt; &gt;
&gt; &gt; it
&gt; &gt;
&gt; &gt;&gt;&gt;isn't clear what's being recommended (or even considered).
&gt; &gt;&gt;
&gt; &gt;&gt;this comment is valid. but since we assume the access routers are
&gt; &gt;&gt;part of the same administrative domain, they are provisioned with
&gt; &gt;&gt;the required certificates to run IKE. (?)
