Description

As already mentioned in this thread https://forum.netgate.com/topic/123554/new-latency-every-30-seconds-with-2-4-2-caused-by-radvd-2-17_3/9 , there is an issue with latency spiking every 30 seconds causing packet loss and other issues. The setup is a LACP Link with vlans on it and mutliple wan gateways. This makes IPv6 unusable!

The debug logs of radvd don't show anything unusual.

History

#1 Updated by Flole Systems over 2 years ago

This still exists in 2.4.4

#2 Updated by Alexander Harrison over 2 years ago

I was seeing the exact same thing

ServicesDHCPv6 Server & RALANDHCPv6 Server

Disabled the above - the issue mostly went away - the frequency dropped 10 fold at least.

#3 Updated by Flole Systems over 2 years ago

As already written in the Forum, I would like to know what NIC and Configuration are you using (LACP etc.).

#4 Updated by Svein Arne Kjerstad over 2 years ago

Can confirm that the bug exists in 2.4.4-RELEASE-p1 (amd64)CE.

LAGG protocol is LACP and vlan on the LAGG, pretty much defaults beside of that.
Nic:
Expansion card
class=0x020000 card=0x00001425 chip=0x50071425 rev=0x00 hdr=0x00
vendor = 'Chelsio Communications Inc'
device = 'T520-SO Unified Wire Ethernet Controller'

Orgianlly I submitted a ticket in the help forum,
https://forum.netgate.com/topic/136362/ping-spikes-2-4-4-xg-1537

Let me know if more details are needed.

#5 Updated by Bianco Veigel 5 months ago

I can confirm, this issue is still present on 2.5.0-DEV. I'm using VLANs on my Onboard Intel(R) PRO/1000 for LAN and stopping radvd instantly solved the packet loss / latency issue.

#6 Updated by Bianco Veigel 5 months ago

After switching from Intel to Realtek I can no longer reproduce the issue.

#7 Updated by Jonathan Black 27 days ago

I'm having an issue with this on 2.5.0-Release . I'm not using LACP, but I do have multiple LANs on VLANs.

#8 Updated by Flole Systems 27 days ago

Could you please provide information on what NIC you are using? To me it seems like an issue with a certain kind of NIC but it doesn't always occur for some reason.

I have this same issue on an Intel I219-V, router on a stick VLANs config: radvd enabled = massive lag spikes at same time as radvd CPU spike, radvd disabled = no more lag spikes (on pfsense 2.5.1 - unable to use workaround from forum as I can't find a radvd 1.x build for FreeBSD 12).

Attempted to update to radvd 2.19_1 but that just results in the following log spam:
Apr 11 20:48:45 radvd 95114 can't join ipv6-allrouters on em0.100

They are both onboard Intel NICs. I think one is the 82574L and the other is the 82579LM.

Just like Daniel above, I also have Vlans. I suspect this happens under a combination of conditions.

#11 Updated by Daniel Cameron 21 days ago

Running radvd manually with -d5 with a ping running at the same time, it appears the latency spikes line up with the 2 second gap in the log between printing addresses and "ready", if anyone knows what it's supposed to be doing then?

[Apr 18 20:48:22] radvd (32525): prefix length for em0.100 is -1

Looks like I did that wrong (grabbed normal FreeBSD release of radvd, not pfSense patched version)

Just updated to 2.6.0 dev snapshot 20210416 - this incorporates the 2.19_1 multicast fix correctly and appears to have now resolved the issue for me (unless it takes a while to show up post reboot, but it previously hasn't).

This also lines up with what I was seeing earlier, the 2 second gap in the logs is when the 2.17 - 2.19 versions of radvd were leaving and rejoining the group every time, it seems that blocks the interface and introduces the latency and BSD 12 multicast fixes in radvd have stopped my issues. No more lag spikes, no more radvd CPU spikes.

A bit over an hour later I still have no latency, but logs are massively filled with:

Apr 19 12:33:01 radvd 71791 attempting to reread config file

every 15 seconds or so, and devices have lost their IPv6 addresses

try my fix listed in https://forum.netgate.com/topic/163009/radvd-can-t-join-ipv6-allrouters-on-hn1/7

to eliminate the "can't join ipv6-allrouters" spam and get a functioning RADVD (2.6.x only)

yep make sense, radvd breaking since 2.6 upgrade lined up with a config change that triggered a radvd reload that obviously fails because it's already joined the group, it hasn't broken since I killed the pid and restarted it, I've made your change as a preventative measure so that if another reload is triggered it starts cold and doesn't break again, cheers.
