I am not sure if this is relevant or not, but one of my EBGP routers (running 1.2.6) has had its BGP crash around 13:00 Monday and 06:20 Tuesday (both times UTC). On both occasions the router was rebooted.

Two other EBGP routers (one running 1.2.6 & the other 1.2.4) connected to other providers showed no problems.

There did not seem to be anything that interesting in the logs, except that frrwatch could not restart it.

In case it relates to a particular update, I am tcpdumping EBGP messages lest it fails again.

All of my routers are monitored for BGP/OSPF via SNMP.

Maybe you have fullview and get full statistics via snmp.
Which parameters do you get via snmp?

7

The only BGP parameters polled are the status of the BGP neighbor and their uptime. It does take a full BGP feed.

Hello,

Dose the servers configuration ar the same ? CPU, Ram … ?

My router exhibited the same behaviour yesterday evening. There was high CPU followed by BGP stopping. The relevant FRR logs are attached. I wonder whether the BGP stopping is a symptom of something else. Neither of my other ebgp routers (with similar config) showed any issues.

I have not yet rebooted the router and have not been through the logs in details, but do have PCAPs of the egbp traffic. It will need to be rebooted by the end of today.

Before rebooting it, is there anything else which the Vyos folks would like to be captured? If it might assist, I could provide remote access for them to take a look.

Can you please write me your server configuration, the CPU, cuz i think i founded the problem on my curent tests.

11

Sanitised config, CPU and memory details are in: 120114-info1.txt (15.9 KB)

It is a virtual machine hosted at Vultr. Similar VMs in my own network are not exhibiting the same problem.

This is strange, cpu is good.

For me was like this.

I used an server poweredge r610 with cpu 2 x Intel X5670 2.93, 32gb ram for 6 mo, never had any problems on the same version.

I changed the server with a smaller one, for power usage, an server with Dell Poweredge R320 1 x Xeon Six Core E5-2430 2.2ghz and the problem started, i was thinking is sompting wrong with it, so i installed on another one same config Dell Poweredge R320 1 x Xeon Six Core E5-2430 2.2ghz, same problem.

So i switch back to my r610 with cpu 2 x Intel X5670 2.93, 32gb, and till now never had this problem.

I truly dont understand if is regarding the server or not, cuz i didnt founded any fix for this

13

Any updates on this?
I too experienced this on VM with 1CPU 6GB RAM (Dell R610 host node)

I was changing import policy (route-map) and got the same issue everyone is getting.

~$ sh ver

Version: VyOS 1.4-rolling-202106251951
Release Train: sagitta

$ sh ip bgp summ
% BGP instance not found

I tried to restart frr bgpd and no dice on that. Rebooting the VM was the fix.

14

Needs to check logs o history.

show log all | match frr

15

Does looks like the logs are not saved as they are local. Not connected to Syslog server.
Any suggestions? Rotates etc.
