RFC 7599, "Mapping of Address and Port using Translation (MAP-T)", July 2015

Source of RFC: softwire (int)

Errata ID: 5225
Status: Reported
Type: Technical

Reported By: Ole Troan

Section 6 says:

In the case of an IPv4 prefix, the IPv4 address field is right-padded
with zeros up to 32 bits.  The PSID is left-padded with zeros to
create a 16-bit field.  For an IPv4 prefix or a complete IPv4
address, the PSID field is zero.

It should say:

The PSID is left-padded with zeros to
create a 16-bit field.  For an IPv4 prefix or a complete IPv4
address, the PSID field is zero.

Notes:

This text has been copied from RFC7597 (MAP-E). While it is correct in the context of MAP-E, for MAP-T the complete IPv4 source address must be embedded in the interface-identifier for correct translation in the case of an IPv4 prefix. Right padding the prefix with zeroes would lead to the translated packet having all zeroes in its source address.

Section Appendix A says:

Example 4:

IPv4 address:            192.0.2.18 (0xc0000212)

It should say:

Example 4:

IPv4 address:            192.0.2.1 (0xc0000201)

Notes:

BMR defines 0 EA bits and IPv4 prefix 192.0.2.1/32, shouldn't the IPv4 address be 192.0.2.1?

Another possible option perhaps would be to change the BMR IPv4 prefix to 192.0.2.18/32 and the IPv6 address of MAP CE to: 2001:db8:0012:3400:0000:c000:0212:0000

Section Appendix A says:

Example 5:

PSID:                    0x20 (provisioned with DHCPv6)

It should say:

Example 5:

PSID:                    0x34 (provisioned with DHCPv6)

Notes:

In IPv4, IPv6 and port range presented in the example the PSID matches to 0x34 and not 0x20:

PSID: 0x34
Available ports (63 ranges): 1232-1235, 2256-2259, ...... ,
63696-63699, 64720-64723
IPv6 address of MAP CE: 2001:db8:0012:3400:0000:c000:0212:0034

Section Appendix A says:

Example 2 - BR:
PSID:  0                  x34 (1232)

Example 4:


It should say:

Example 2 - BR:

PSID:                     0x34 (1232)

Notes:

There is a long space between 0 and x34
