The following errata report has been verified for RFC7052, "Locator/ID Separation Protocol (LISP) MIB". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=7052&eid=4235 -------------------------------------- Status: Verified Type: Technical Reported by: Isidor Kouvelas <kouvelas@cisco.com> Date Reported: 2015-01-17 Verified by: Brian Haberman (IESG) Section: 7 Original Text ------------- Example 3: As an example where LCAF is used, suppose that the IPv4 EID-Prefix stored is 192.0.2.0/24 and it is part of LISP Instance ID 101. In this case, the values within lispMapCacheEntry would be: lispMapCacheEidLength = 11 lispMapCacheEid = 16387, 7, 2, 101, 1, 192.0.2.0, 24 ... [skip] ... where 11 is the total length in octets of the next object (lispMapCacheEID of type LispAddressType). Then, the value 16387 indicates the LCAF AF (see the IANA-ADDRESS-FAMILY-NUMBERS-MIB), the value 7 indicates that the LCAF AF is 7 octets in length in this case, 2 indicates that LCAF Type 2 encoding is used (see the LCAF document), 101 gives the Instance ID, 1 gives the AFI (per the IANA-ADDRESS-FAMILY-NUMBERS-MIB) for an IPv4 address, 192.0.2.0 is the IPv4 address, and 24 is the mask-length in bits. Note that the lispMapCacheEidLength value of 11 octets is used to compute the length of the last field in lispMapCacheEid to be 1 octet -- as computed by 11 - (2 + 1 + 1 + 1 + 1 + 4) = 1. Corrected Text -------------- Example 3: As an example where LCAF is used, suppose that the IPv4 EID-Prefix stored is 192.0.2.0/24 and it is part of LISP Instance ID 101. In this case, the values within lispMapCacheEntry would be: lispMapCacheEidLength = 14 lispMapCacheEid = 16387, 10, 2, 101, 1, 192.0.2.0, 24 ...

Note that the lispMapCacheEidLength value of 14 octets is used to compute the length of the last field in lispMapCacheEid to be 1 octet -- as computed by 14 - (2 + 1 + 1 + 3 + 2 + 4) = 1. Notes ----- The Instance ID within the type 2 LCAF is 24 bits and requires 3 octets (incorrectly calculated as 1) The AFI within the LCAF type 2 requires 2 octets (incorrectly calculated as 1) -------------------------------------- RFC7052 (draft-ietf-lisp-mib-13) -------------------------------------- Title : Locator/ID Separation Protocol (LISP) MIB Publication Date : October 2013 Author(s) : G.
