The following errata report has been submitted for RFC5847,
"Heartbeat Mechanism for Proxy Mobile IPv6".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=5847&eid=2302

--------------------------------------
Type: Technical
Reported by: Alfred Hoenes <ah@TR-Sys.de>

Section: 3.1, pg. 5

Original Text
-------------
A PMIPv6 node (MAG or LMA) matches every received Heartbeat Response
to the Heartbeat Request sent using the sequence number. Before
sending the next Heartbeat Request, it increments a local variable
<< page break >>
| MISSING_HEARTBEAT if it has not received a Heartbeat Response for the
| previous request. When this local variable MISSING_HEARTBEAT exceeds
a configurable parameter MISSING_HEARTBEATS_ALLOWED, the PMIPv6 node
concludes that the peer PMIPv6 node is not reachable. If a Heartbeat
! Response message is received, the MISSING_HEARTBEATS counter is
reset.

Corrected Text
--------------
A PMIPv6 node (MAG or LMA) matches every received Heartbeat Response
to the Heartbeat Request sent using the sequence number. Before
sending the next Heartbeat Request, it increments a local variable
| MISSING_HEARTBEATS if it has not received a Heartbeat Response for
| the previous request. When this local variable MISSING_HEARTBEATS
exceeds a configurable parameter MISSING_HEARTBEATS_ALLOWED, the
PMIPv6 node concludes that the peer PMIPv6 node is not reachable.
If a Heartbeat Response message is received, the MISSING_HEARTBEATS
counter is reset.

Notes
-----
Rationale:
The RFC text varies between singular and plural form of the name
of the local variable. A single name is necessary for consistency.
Paraphrasing from MIB doctor guidelines, counter variables should
always be in plural form. Additionally, the related configurable
parameter is called "MISSING_HEARTBEATS_ALLOWED " in the RFC.
Therefore, "MISSING_HEARTBEATS" is chosen above as the appropriate
form and the instances of "MISSING_HEARTBEAT" are changed to the
plural form.

Instructions:

This errata is currently posted as "Reported". If necessary, please
