Type: Technical
Reported by: Quentin Armitage <quen...@armitage.org.uk>

Section: 7.1

Original Text
-------------
 * It MUST verify that the VRID is configured on the receiving
   interface and the local router is not the IPvX address owner
   (Priority = 255 (decimal)).

If any one of the above checks fails, the receiver MUST discard the
packet, SHOULD log the event (subject to rate-limiting), and MAY
indicate via network management that an error occurred.

Corrected Text
--------------
 * It MUST verify that the VRID is configured on the receiving
   interface and the local router is not the IPvX address owner
   (Priority = 255 (decimal)).

 * It MUST verify that IPvX Addr Count is non zero.

If any one of the above checks fails, the receiver MUST discard the
packet, SHOULD log the event (subject to rate-limiting), and MAY
indicate via network management that an error occurred.

Notes
-----
The only change above is adding:
  * It MUST verify that IPvX Addr Count is non zero.

This is due to section 5.2.5 requiring it:

5.2.5. IPvX Addr Count

The IPvX Addr Count field is the number of either IPv4 addresses or IPv6 
addresses contained in this VRRP advertisement. The minimum value is 1. If the 
received count is 0, the VRRP advertisement MUST be ignored.

Instructions:
-------------
This erratum is currently posted as "Reported". (If it is spam, it 
will be removed shortly by the RFC Production Center.) Please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
will log in to change the status and edit the report, if necessary.
