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 M6Bone project fejlesztett hozzá Linux támogatást, amely elérhető a 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

Konfigurációs lépések

1. IPv6 stack aktiválás

    #in file /etc/rc.conf"
    ipv6_enable="YES"

2. IPv6 routing engedélyezés

    #in file /etc/rc.conf
    ipv6_gateway_enable="YES"

3. Router Advertisement letiltása - ha nem ez a rendes router is....

    #in file /etc/rc.conf
    rtadvd_enable="NO"

4. Manuális IPv6 cím konfigurálás az interfészre on an interface
5. Default route beállítása

    #in file /etc/rc.local
    route add -inet6 default @ipv6_default_router%xl0

6. 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

7. 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;
   
   #syntax : <switch_register_threshold> <rate> [number] <interval> [number]
   #default rate = 50000 interval = 20s
   #samples :
   #TODO : not tested
   #switch_register_threshold rate 54389 interval 45;
   #switch_register_threshold;
   
   #syntax : <switch_data_threshold> <rate> [number] <interval> [number]
   #default rate = 50000 interval = 20s
   #TODO : not tested
   #samples:
   #switch_data_threshold interval 100 rate 1000;
   
   #syntax : <default_source_metric> [number]
   
   #default_source_metric 1243;
   #syntax : <default_source_preference> [number]
   
   #default_source_preference 123 ;
