Cluster Falover after every change on pbr, routing, ospf,...

Gro_Tea — Wed, 13 May 2020 14:22:28 GMT

Hello,

I have two 5600 Appliances runninh in HA on R80.30 , but bevavoiur was already on 80.10.

Everytime I do a change in PBR Settings (adding Table etc), add an interface, or add an ospf route distribution, the node on which I work gets degraded to down. If I do this on the primary node, a failover occurs.

Hi @Gro_Tea

Maybe this sk will help you:

or

Re: Cluster Falover after every change on pbr, routing, ospf,...

Gro_Tea — Thu, 14 May 2020 13:45:51 GMT

Hello Heiko,

thanks for reply, I checked the links...

The Problem is, that the Pnote is only a few seconds.

Pnote ON at 10:08:23 degrades the Member from Active to down. Then without any interaction the status resumes from down to standby (because the other node is now active) only 8 seconds later.

This happens while doing changes in routing contexts (create Interface, modify/add PBR,...). Very annoying when you need to do changes and almost every action causes a failover.

Regrads,

Frank

Have you seen this SK:

sk109051: Troubleshooting Dynamic Routing - Cluster XL - PNOTE issues

If the routed pnote has a Timeout of "None" in the output of cphaprob -l list, even the slightest blip in that process will cause a failure of that pnote and an instant failover. Perhaps you have a very large routed configuration and when it is changed the daemon goes "out to lunch" parsing the config for just long enough to trip the pnote? The 5600 is not the speediest box in the world and that may be part of the issue.

It might be interesting to try increasing the timeout for the routed pnote to give it a little more leeway. Would not recommend going beyond 2 or 3 seconds though.

Gro_Tea — Fri, 15 May 2020 13:06:28 GMT

Hi Tim,

thanks, that sounds interesting and I want to try it. For increasing the timeout do I have to unregister the device and register it with new timeout?

cphaprob -d routed [-p] unregister

cphaprob -d routed -t <timeout in sec> -s ok [-p] register

If I do a "cphaprob -d routed unregister" it answers me with the list of usage...

How do I increase the timeout?

Thanks

Frank

Actually check this SK first, as it is not immediately obvious how to modify the timeout for the routed pnote:

Re: Cluster Falover after every change on pbr, routing, ospf,...

Gro_Tea — Fri, 15 May 2020 15:09:46 GMT

Hi,

the mentioned checkbox for PNOTE Reporting has gone with 77.30 and is disabled by default.

Seems not easy setting timeout for device routed...

Thanks

Hi, Frank!

Did you found any solution for this trouble with failover after creating interface, adding route, and so on?

Now i have same trouble, but can't found how to fix this.

Are you applying your changes first on the standby or active?

Re: Cluster Falover after every change on pbr, routing, ospf,...

ajax — Mon, 16 Jun 2025 10:09:24 GMT

Hello! On Active first. Is this not right?

Hello! Thank you for answer. I understand about adding / deleting interfaces, but we have failover when add / edit ip routes. If we add static route or redistribute static route to ospf on active node, after few second we get failover. You can see messages on active node (i added part of messages file).

Chris_Atkinson — Tue, 17 Jun 2025 11:56:50 GMT

For context are you seeing impact from the failover or you just observe that it happens...

Are you using graceful restart?

Are the ospf router-id aligned for both members?

Re: Cluster Falover after every change on pbr, routing, ospf,...

Oliver_Fink — Tue, 17 Jun 2025 11:29:44 GMT

In the logs you see that routed gets started. I guess that is because it was stopped before – maybe to reload configuration. But routed is a registered device to the cluster.

# cphaprob -l li

[…]

Registered Devices:

[…]

Device Name: routed
Registration number: 2
Timeout: none
Current state: OK
Time since last report: XXXX sec

If a registered device is not availabe the cluster fails over.

ajax — Tue, 17 Jun 2025 12:09:11 GMT

Yes, all 4 nodes have same router-id in OSPF process.

About impact from failover - i can't say exactly, but anyway we need to understand, why we get failover after add/edit routes and how to fix this one.

Re: Cluster Falover after every change on pbr, routing, ospf,...

ajax — Tue, 17 Jun 2025 12:11:06 GMT

Thank you for answer!

I checked , and all members of cluster have registered devices: routed , and status OK.

I checked on my lab with virtual CP , and when i redistribute static route or direct connected interface to ospf , i don't have this messages and don't have failover (but in real CP cluster have this messages! And after this messages we get failover):

May 15 09:06:25 2025 cp-int-1 routed[31560]: [routed] NOTICE: task_cmd_init(145): command subsystem initialized.
May 15 09:06:25 2025 cp-int-1 routed[31560]: [routed] NOTICE: Start routed[31560] version routed-11.06.2024-17:55:19 instance 0

May 15 09:06:25 2025 cp-int-1 routed[31560]: routed_syslog_on: tracing to "/var/log/routed_messages" started

Somebody know, what mean this messages?

Frank had the issue 5 years ago, so your question is kind of... I would suggest to create a post yourself !

Re: Cluster Falover after every change on pbr, routing, ospf,...

Oliver_Fink — Tue, 17 Jun 2025 13:35:11 GMT

Yes, the process routed gets started – as I wrote. Before that the process routed seems to be stopped. That is why the cluster fails over. After the (re)start of the routed everything is fine again – except that the cluster runs on the other node. The cluster fails over in the time between stop and start of the routed process, I guess.

Hello!

I found solution for trouble with failover after every change of routing.

It turned out that the problem was that we had a static route to a subnet for NAT registered on the gateways and the cluster address of one of the interfaces was specified as the next-hop address. Then this static route was redistributed to the OSPF for neighboring routers. And the gateways in routed_messages complained that the next-hop address for these static routes belonged to the local interface, which was kind of wrong. As soon as I deleted these static routes, the failover error disappeared and now after changing the routing, the node activity does not change.

I have this error on stand, where i simulate same problem (you can see in the attachment)
