whar is the root cause? thank you.

[troglobit]

1. What version of pimd are you using?
2. The multicast routing stack only allows one routing daemon at a time (except if you use policy routing/tables)
3. The root cause is that you probably have another multicast routing daemon running, e.g. smcrouted, mrouted, or more likely another pimd instance in the background

hi，it seems I did not install the mrouted,smcrouted,how can I find the Another multicast routing application? which port is listening by the pimd?

root@ubuntu:/etc# smcrouted

Command 'smcrouted' not found, did you mean:

command 'smcroute' from deb smcroute

Try: apt install

root@ubuntu:/etc# mrouted
mrouted: command not found

[troglobit]

If you've installed pimd as a .deb packlage from Ubuntu then it's likely already running in the background. Check your ps output, e.g.

ps fax |grep pimd

[shockingchen]

thank you,it seems can be started. I did not do anything change,just reboot the linux today?

[troglobit]

OK, not a bug then, so closing this issue report.
