Issue #1325 has been updated by Lan Wang.
<ul>
</ul>
<p>Vince:</p>
<p>The statement "CAPTURE: indicates that no shorter prefix can be used; overrides CHILD_INHERIT. This flag applies on the prefix: if any route of a prefix has this flag, the prefix will have this flag." means just for that particular prefix, not longer prefixes.
The prefix (e.g., /ndn/edu/memphis) can have multiple routes. If any of those routes has this flag, the prefix has this flag set.</p>
<p>For your question "Does that not mean if an entry has its CAPTURE flag set, then its children would also have their capture flag set?", I think the answer is no. What Obaid said is the following: If an entry A has its CAPTURE flag set, the children cannot
use the nexthop of A's ancestors. This is different from setting a child's capture flag, which means that child cannot use its own ancestors' nexthops (including A's).</p>

<p>For everyone: I would like to get comments on two issues and reach an agreement:</p>
<ol>
<li>
<p>do you think this is correct for the CAPTURE flag: "This flag applies on the prefix: if any route of a prefix has this flag, the prefix will have this flag."? In contrast, the INHERIT flag applies only to (prefix, nexthop). Do you think this is the correct
behavior for INHERIT?</p>
</li><li>
<p>do you think the CAPTURE flag on prefix A should block all A's children from using A's ancestors' nexthops?</p>
</li></ol>
