Abstract:
The IP Router Alert Option is an IP option that alerts transit routers to
more closely examine the contents of an IP packet. The Resource reSerVation Protocol (RSVP), Pragmatic General
Multicast (PGM), the Internet Group Management Protocol (IGMP), Multicast Listener Discovery (MLD), Multicast Router Discovery (MRD),
and General Internet Signaling Transport (GIST) are some of the protocols that make use of the
IP Router Alert Option. This document discusses security aspects and usage guidelines around
the use of the current IP Router Alert Option, thereby updating RFC 2113 and
RFC 2711. Specifically, it provides recommendations against using the Router Alert in
the end-to-end open Internet and identifies controlled environments where protocols depending
on Router Alert can be used safely. It also provides recommendations about protection
approaches for service providers. Finally, it provides brief guidelines for Router
Alert implementation on routers. This memo documents an Internet Best Current Practice.
