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 thereby updating RFC2113 and RFC2711.
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.
