PIM-HELLO-OPTIONS - Per [RFC2362]

(last updated 2003-04-09)

The Protocol Independent Multicast routing protocol (PIM)
specified in [RFC2362] uses an extensible Hello packet
format.  Hello packet options may be assigned First Come
First Serve, as described in [RFC2434].  First Come First
Serve assignments expire in one year; permanent assignments
require a specification ("Specification Required" as
described in [RFC2434]).

The current assigned values for these parameters are
listed here.
