= IPv6 multicast router konfiguráció *bsd rendszerek pim6sd segítségével =

== Bevezetés ==
A pim6sd kódja eredetileg a Kame BSD stack-hez lett kifejlesztve a Wide konzorcium által. Ez az idők folyamán külön fejlődésnek indult. Először az [[http://www/m6bone.net|M6Bone]] project fejlesztett hozzá Linux támogatást, amely elérhető a  [[http://clarinet.u-strasbg.fr/~hoerdt/dev/pim6sd_linux/|PIM6SD Linux]] oldalon. A fejlesztés ezek után a sourceforge-ra került át. Elérhető a http://mcast-tools.sourceforge.net/ címen.

=== Alapvető funckiók ===
 * PIM SM/SSM
 * BSR (PIM-SM draft) vagy statikus RP konfiguráció (KAME snapshottól függően)
 * RP funkcionalitás
 * IPv6 in IPv6 tunneling

=== M6Bone által hozzá fejlesztések ===
 * BSR border
 * BSR filtering
 * Statically configured RPs
 * Default IPv6 multicast route
 * IPv6 - IPv4 multicast dynamic gateway on RP
 * embedded RP addresses
=== Sourceforge fejlesztések ===

== Konfigurációs lépések ==

 1.   IPv6 stack aktiválás
 {{{
 #in file /etc/rc.conf"
 ipv6_enable="YES"
 }}}
 1.   IPv6 routing engedélyezés
 {{{
 #in file /etc/rc.conf
 ipv6_gateway_enable="YES"
 }}}
 1.  Router Advertisement letiltása - ha nem ez a rendes router is....
 {{{
 #in file /etc/rc.conf
 rtadvd_enable="NO"
 }}}
 1. Manuális IPv6 cím konfigurálás az interfészre on an interface
 1. Default route beállítása
 {{{
 #in file /etc/rc.local
 route add -inet6 default @ipv6_default_router%xl0
 }}}
 1. IPv6 PIM Sparse-Mode (pim6sd) daemon installálása
 Installálás port-ból:
 {{{
 cd /usr/ports/net/mcast-tools/ && make install clean
 }}}
 Installálás package-ként:
 {{{
 pkg_add -r mcast-tools
 }}}
 1. Configuration of PIM SM
 A pim6sd.conf manuálja minden opciót leír.
 {{{
#The timer granularity.
#More this value is small,more pim6sd will be accurate
#default if not specified : 5
#BE SURE to have to same granularity on ALL routers,
#otherwise....

#granularity 5;

#syntax : phyint <interface> <disable> <metric> [metric] <preference> [preferenc
e]
#metric and pref are for the asserts messages
#samples :

#phyint ed1 disable;
#phyint de0 disable;
#phyint ed0 disable;
#phyint gif0 disable;

#---------------Protocol timer specifications---------------------------#
#Notes : theses value are the default spec value!
#do not touch it if you don't know what you do!!
#you MUST change theses values according to the granularity value!
#syntax :  'hello_period <number> <coef>'.
# number is the period in second between 2 hello messages
# and coef is the coef to determine the hello holdtime=hello_period*coef
# default if not specified: 30 3.5

#hello_period 30 3.5;

#syntax :  'join_prune_period <number> <coef>'.
# number is the period in second between 2 join/prune messages
# and coef is the coef to determine the join/prune holdtime=join_prune_period*co
ef
# default if not specified : 60 3.5

#join_prune_period 60 3.5;

#syntax :  'data_timeout <number>'.
# number is the time after which (S,G) state for a silent source will be deleted
# default if not specified  : 210

#data_timeout 210;

#syntax :  'register_suppression_timeout <number>'.
# This is the mean interval between receiving a Register-Stop and allowing
#Register to be send again.
# default if not specified  : 60

#register_suppression_timeout 60;

#syntax :  'probe_time <number>'.
#This is the time between sending a null Register and the Register-Suppression-T
imer
#expiring unless it is restarted by receiving a Register-Stop.
#default if not specified : 5

#probe_time 5;

#syntax :  'assert_timeout <number>'.
#this is the interval between the last time an Assert is received and the time a
t which the
#assert is timeout
#default if not specified : 180

#assert_timeout 180;
#syntax : <cand_rp> <interface> <time> [time] <priority> [priority]
#and time can't be <  10
#you can just type cand_rp,
#samples :
#cand_rp;
#cand_rp de0;
#cand_rp ed0 priority 0 time 6;

#syntax : <group_prefix> <multicast address>/<prefix length>
#group_prefix ff06::15
#default if not specified : ff00::/8
#samples:
#group_prefix ff1e::15/128;
#group_prefix ff2e::/16;

#syntax : <cand_bootstrap_router> <interface> <priority> [priority] <time> [time
]
#Typically, you can simply set cand_bootstrap_router for a candidate bootstrap
#router. All other parameters are optional.
#the bootstrap period is configurable, BUT the holdtime of a bootstrap
#router is not in the fields of a bootstrap message : it is hard-coded
#in the pim6sd include file!
#So be sure to have a time < PIM_BOOTSTRAP_TIMEOUT (file pimd.h )
#cand_bootstrap_router de0 priority 15 time 5;
