Was that debug useful?

So, it seems this behaviour is more harmful to the network than just
spamming a log on the NM host.

It's causing a message storm with the router that is sending the
multiple RAs in that NM is sending RS messages in response to the RAs
crushing the router with RS messages.

Given that, can any more importance be put on this issue?

Hi Brian,

It's not clear to me what you mean.

Do you mean, that the many RA received at NetworkManager cause
NetworkManager to send too frequent RS (in turn, repeating a vicious

I wouldn't see that from the log. There are no log lines about
additional router solicitations sent by NetworkManager.

Also, NM only sends RS based on timeouts, not based on RAs that it
receives [1].

can you clarify what you think is the harmful behavior? Also, does
tcpdump/wireshark show that NM sends too many RS?
