The IP Router Alert Option is an IP option that alerts transit
routers to more closely examine the contents of an IP packet.
Resource reSerVation Protocol (RSVP), Pragmatic General Multicast
(PGM), Internet Group Management Protocol (IGMP), Multicast Listener
Discovery (MLD), Multicast Router Discovery (MRD) and General
Internet Signalling 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. Specifically, it provides recommendation
against using the Router Alert in the end-to-end open Internet as
well as identify controlled environments where protocols depending on
Router Alert can be used safely. It also provides recommendation
about protection approaches for Service Providers. Finally it
provides brief guidelines for Router Alert implementation on routers.
