| - Check the source is issuing multicast packets with TTL high enough |
| - Check the multicast packets are not being dropped due to |
| - Two easy options to test IGMPv3 joins from the receiver host: |
| 1) Configure pimd on the receiver host with "ip igmp join": |
| ip igmp join 239.1.1.1 1.1.1.1 |
| 2) Use the test_igmpv3_join command-line utility: |
| test_igmpv3_join eth0 239.1.1.1 1.1.1.1 |
| - The following command generates a 100-kbps multicast stream for |
| channel 1.1.1.1,239.1.1.1 with TTL 10 and 1000-byte payload per UDP |
| packet (to avoid fragmentation): |
| nepim -b 1.1.1.1 -c 239.1.1.1 -T 10 -W 1000 -r 100k -a 1d |
| - Remotely you can receive that stream by running: |
| nepim -j 1.1.1.1+239.1.1.1@eth0 |
| (Remember of enabling both "ip pim ssm" and "ip igmp" under eth0.) |
| test pim receive hello eth0 192.168.0.2 600 10 111 1000 3000 0 |
| test pim receive join eth0 600 192.168.0.1 192.168.0.2 239.1.1.1 1.1.1.1 |
