4.2.1 INTRODUCTION
4.2.1 INTRODUCTION
Routers MUST implement the IP protocol, as defined by [INTERNET:1].
They MUST also implement its mandatory extensions: subnets (defined
in [INTERNET:2]), IP broadcast (defined in [INTERNET:3]), and
Classless Inter-Domain Routing (CIDR, defined in [INTERNET:15]).
Router implementors need not consider compliance with the section of
[INTRO:2] entitled "Internet Protocol -- IP," as that section is
entirely duplicated or superseded in this document. A router MUST be
compliant, and SHOULD be unconditionally compliant, with the
requirements of the section entitled "SPECIFIC ISSUES" relating to IP
in [INTRO:2].
In the following, the action specified in certain cases is to
silently discard a received datagram. This means that the datagram
will be discarded without further processing and that the router will
not send any ICMP error message (see Section [4.3]) as a result.
However, for diagnosis of problems a router SHOULD provide the
capability of logging the error (see Section [1.3.3]), including the
contents of the silently discarded datagram, and SHOULD count
datagrams discarded.
