[solved] PPPoE IA-PD woes

Actually same as when it works… I see nothing special there...

So it appears dhcp6c is working, and by the look of it so is RTSOLD. Hmm, pppoe thing. Not even sure if it's related or not.

Try this, see if it makes any difference. Just add it on the end of the others.

Nuts… Didn't test it.. Give me ten minutes.

maverick_slo · Mar 12, 2017, 10:19 AM

Fixed it myself…
Just removed extra ")"... testing now

maverick_slo · Mar 12, 2017, 10:20 AM

Not helped

Guest · Mar 12, 2017, 10:53 AM

Baffled. ???

So it works unless you pull the link for more than 'n' seconds though. So what's changing after that 'n' seconds that's preventing a recovery?

Do we need to send another RA and reset the whole sequence, we know that dhcp6c is running bit a kick up the bum with a SIGHUP did not fix it. Try running the RTSOLD script from the shell and see if that kicks anything into life. It should report lock in place etc but will send out an RS.

Yeah link flap for 10 seconds or less is ok… As soon as last lcp is missed and pppoe starts reconnecting if I then plug utp back in no ipv6 address on pppoe...
How do I run rtsold script from shell?
Will try it in hour or 2 when I come home...

In /Var/etc you should see a script something like rtsold_{IFACE}_script.sh, where {IFACE} is the interface you are interested in.

To run it, just do ./ rtsold_{IFACE}_script.sh

I'll squash down those commits it's getting untidy.

OK, I've squashed all those commits down to a single pair.

When I run rtsold script:

Mar 12 13:15:49 	php-fpm 	72012 	/rc.newwanipv6: rc.newwanipv6: No IPv6 address found for interface PPPOE [opt2].
Mar 12 13:15:49 	php-fpm 	72012 	/rc.newwanipv6: rc.newwanipv6: Info: starting on pppoe0.
Mar 12 13:15:49 	php-fpm 	75079 	/rc.filter_configure_sync: Gateways status could not be determined, considering all as up/active. (Group: GWGRP_IPv6)
Mar 12 13:15:47 	rtsold 		RTSOLD Lock in place - sending SIGHUP to dhcp6c
Mar 12 13:15:47 	rtsold 		Received RA specifying route for interface opt2(pppoe0)

So still no IPv6 address on iface PPPOE.
Weird.

maverick_slo · Mar 12, 2017, 12:31 PM

I think it will only get ipv6 address when connecting and no later…

Only thing that is 1000% is disconnect/connect from interfaces page or save/apply on pppoe iface settings page.
In those 2 cases ipv6 is ALWAYS assigned.

Guest · Mar 12, 2017, 12:34 PM

Yes, I was doing a bit of reading, think it's a pppoe thing - note my earlier comment about changing ISP, I'll find out soon!

Just remembered, my current ISP is a little wierd in that respect too, if I don't send a dhcp6 solict within a set period after a v4 solicit then no ipv6. The v4 solicit also contains the credentials so the only solution is drop the link, wait 5 minutes until the ISP's BNG resets and start the login again.

maverick_slo · Mar 12, 2017, 12:33 PM

Ahh we just both posted at the same time :)

See above I`ve edited post…

Yeah, this is pppoe thingie I think that too...

PPPoE is really tricky sometimes...

But you`ve fixed flapping issue thanks a bunch!!

Guest · Mar 12, 2017, 12:36 PM

Good. Would you like to roll back the patches and apply the consolidated pair and see if it's OK. I can then comment on that PR that at least one person has tested it and it's OK.

maverick_slo · Mar 12, 2017, 12:52 PM

I already did that and using it
Works great.

Guest · Mar 12, 2017, 12:53 PM

Another happy customer! 8)
