"Distributing the Segment Routing over IPv6 (SRv6) Locator Using DHCPv6"

Type: Technical
Reported by: Paul Aitken <[email protected]>

Section 4.2 says:

Original Text
-------------
IALocator-Options: Options associated with this SRv6 Locator. A
variable-length field (determined by subtracting the length of
SRv6-Locator from Option-Len minus 12). The status code
NoSRv6LocatorAvail indicates the server has no locators available
to assign to the IA_SRV6_LOCATOR(s).

Corrected Text
--------------
IALocator-Options: Options associated with this SRv6 Locator. A
variable-length field (determined by subtracting the length of
SRv6-Locator from Option-Len minus 16). The status code
NoSRv6LocatorAvail indicates the server has no locators available
to assign to the IA_SRV6_LOCATOR(s).

Notes
-----
Correct "12" to "16".

Section 4.2 defines: "Option-Len: 16 + the length of SRv6-Locator + the
length of the IALocator-Options field in octets."

Therefore the length of IALocator-Options is  Option-Len − 16 −
length(SRv6-Locator) , i.e. "Option-Len minus 16," not "Option-Len minus
12."

The erroneous "12" may have been carried over from the IA_SRV6_LOCATOR
option in Section 4.1, whose fixed portion (IAID + T1 + T2 = 12 octets) is
correctly "Option-Len minus 12."
