Example
Almost minimal setup where multicast routing is necessary:
multicast sender (server);
multicast receiver (client);
two routers running PIM between them.
Multicast traffic in this example will be destined to address 224.0.1.20
Traffic flow:
Sender -- (subnet I) --> Router A -- (subnet II) --> Router B -- (subnet III) --> Receiver
Router A will be configured as Rendezvous Point.
Enable PIM and IGMP router A:
[admin@A] > routing pim interface add
[admin@A] > routing pim interface p
Flags: X - disabled, I - inactive, D - dynamic, R - designated-router,
v1 - IGMPv1, v2 - IGMPv2, v3 - IGMPv3
# INTERFACE PROTOCOLS
0 v2 all pim
igmp
1 DRv2 ether3 pim
igmp
2 DR register pim
Configure static Rendezvous Point:
[admin@A] > routing pim rp add address=<IP of router A>
Enable PIM and IGMP router B:
[admin@B] > routing pim interface add interface=ether1
[admin@B] > routing pim interface p
Flags: X - disabled, I - inactive, D - dynamic, R - designated-router,
v1 - IGMPv1, v2 - IGMPv2, v3 - IGMPv3
# INTERFACE PROTOCOLS
0 Rv2 ether1 pim
igmp
1 DR register pim
Configure static Rendezvous Point:
[admin@B] > routing pim rp add address=<IP of router A>
Add route on multicast sender:
# ip route add 224.0.1.20/32 via <IP of router A>
Start sender and receiver programs. You can either write simple programs yourself, or use any of these:
MGEN is a program that can be used to send or receive multicast traffic, etc: http://cs.itd.nrl.navy.mil/work/mgen/index.php
Alternatively, mtest is a bare-bones sender/receiver program available from: http://netweb.usc.edu/pim/pimd/
And hey, it works! Client should receive data now.
Только вот незадача. Не могу найти у себя этот PIM... Его чтоли отдельно надо устанавливать?
Может быть кто-то фотоотчет сделает? Так как глядишь, а через год ИП ТВ станет уже де факто.
