Bug#896431: radvd: Periodic restart required to keep advertising
Source: radvd Followup-For: Bug #896431 It appears my issue was not related to radvd actually. I had two instances of dhclient and I believe, my ISP's router removed some prefix routes on their routers, after some timeout. I am certain that I dones some radvd restarts in the past and that it continued working after that for a day or less. But I think it was ultimately dhclient issue. radvd was broadcasting routes (inspected with tcpdump) all the time, so restart was not required. But again, I know for the fact that restarting radvd in the past usually helped. No idea why. I found it is dhcp issue, because I lost routing, but the default route was correct on my LAN host and tcpdump was showing everything is ok, and restarting radvd didn't help. But restarting dhcp did help. I fixed my dhcp issue with configuration, and I have no stable IPv6 routing. Please close the bug. Thanks!

Seen that, but not the whole landscape where the radvd fails. Please provide more information about the network plan. Yes, I think we have now two problems. 1. How and why is radvd is used? ( What is it's purpose? ) 2. The reported "Periodic restart required to keep advertising" Groeten Geert Stappers P.S. FWIW: My radvd keeps advertising IPv6 routes without restarting.

I can investigate more, for example how long exactly it takes until I need to restart it. And check if maybe it have something to do with my dhcp client setup. But from what I see the dhcp client is still working just fine, is renewing addresses fine (and the IPv6 works fine from my router all the time, and the internal LAN interface also keeps IPv6 address and routes correctly all the time).

Source: radvd Followup-For: Bug #896431 Hi, I was probably reporting reportbug using different computer that has sid. The problem is on my router computer that is using stretch. I will use stretch-backports, update radvd and see if this helps.

I have no idea why, but I need to do /etc/init.d/radvd restart every few hours
to keep everything working on my network correctly.
I have static IPv6 prefix.
