"R" bit in Map-Reply message format (comment 22 reported by Y. Rekhter)

Description

Section 6.1.4:

R: when this bit is set, the locator is known to be reachable from

the Map-Reply sender's perspective.

The utility of this bit is never explained and it's not clear how one would make good use of it. I.e., 1 means the sender thinks the given locator is reachable, but 0 is just a question mark.

Here is the new text (from -11 version):

R: set when the sender of a Map-Reply has a route to the locator in

the locator data record. This receiver may find this useful to
know when determining if the locator is reachable from the
receiver. See also Section 6.4 for another way the R-bit may be
used.

I'd like to propose the following replacement to the above:

R: set when the sender of a Map-Reply has a route to the locator in

the locator data record (note that since having the route, by itself,
does not imply that the locator is up, having
the R bit set does not imply that the locator is up).
This receiver may find this useful to know when determining if the
locator could be reachable from the receiver.
See also Section 6.4 for another way the R-bit may be used.

The issue has been fixed in version -12 of the draft as described in section B.1:

  • Tracker item 108. Make clear the R-bit does not define RLOC path reachability.
