Bug #448

pimd is running away on interior router

Description

I installed two interior routers. I noticed that the load was always above 1 on those routers (the exterior gateway was ok), pimd was the culprit.

I disabled pimd, which doesn’t have much use at the moment (since I don’t use IPv6 multicast applications). And as we don’t have hnetd atm to delegate IPv6 prefixes and I’m not bothering to try, this is a theory as to why pimd is only running away on the interior routers; the exterior router has global IPv6 addresses.

Attached are dmesg.txt and logread.txt files of the complaints it is producing.

Actually, pimd is mostly for ipv4 multicast.

I am not seeing any problems here, but my own network is mostly
running mildly older cero code.
