The following errata report has been verified for RFC7052,
"Locator/ID Separation Protocol (LISP) MIB". 

You may review the report below and at:

Status: Verified
Type: Technical

Reported by: Isidor Kouvelas <kouvelas@cisco.com>
Date Reported: 2015-02-04
Verified by: Brian Haberman (IESG)

Section: 7

Original Text
        "RFC 6830, Section 14.2 and
         LISP Canonical Address Format (LCAF), Work in Progress,
         March 2013."

Corrected Text
        "RFC 6830, Section 14.2 and
         LISP Canonical Address Format (LCAF), Work in Progress,
         March 2013."

The minimum octet string length of 5 specified for the LispAddressType is incorrect. The smallest non-empty address is an IPv4 address that is not using the LCAF format to include an instance ID. This requires 8 octets (see example 1 above keeping in mind that the AFI requires 2 octets). However, in many places in the MIB definition the LispAddressType is used as the type for attributes where “unspecified” is a valid return. For example in lispEidRegistrationLastRegisterSender, an EID prefix that is configured on a Map-Server may not have any active registrations. To encode the absence of an address the minimum length of zero should be allowed.
