RFC 5135, "IP Multicast Requirements for a Network Address Translator (NAT) and a Network Address Port Translator (NAPT)", February 2008Source of RFC: behave (tsv)
Errata ID: 1319
Status: Held for Document Update

Section 4.1, pg.6 says:
REQ-7: The NAT MUST NOT forward Local Network Control Block | (224.0.0/24) [RFC3171] (also known as "link-local multicast") traffic from its 'inside' interface(s) to its 'outside' interface.
It should say:
REQ-7: The NAT MUST NOT forward Local Network Control Block | (22.214.171.124/24) [RFC3171] (also known as "link-local multicast") traffic from its 'inside' interface(s) to its 'outside' interface.
Location is end of Section 4.1, near the bottom of page 6.
This correction also needs to be applied to the re-statement
of REQ-7 in Section 5 (mid-page 10).
The basic "strategic" document for CIDR notation now is BCP 122,
RFC 4632, and that document clearly states (in section 3.1, at
the bottom of page 5):
| [...] In CIDR notation, a prefix is shown as a 4-octet
quantity, just like a traditional IPv4 address or network number,
followed by the "/" (slash) character, followed by a decimal value
between 0 and 32 that describes the number of significant bits.
Also being a BCP, RFC 5135 should follow this rule.
