My BGP sessions are crashing since some days with state NoNeg.
After rebooting Vyos the status is on “Active” for some minutes, sending and receiving prefixes works during this time.
After some minutes state changes to NoNeg again.
No config change done since months, BGP worked flawlessly until now.
I’m currently on 1.3-rolling-202011080217, with the latest release the issue is the same.
Exaple config:
Any idea what causes this issue?
Try to check
show ipv6 bgp summary
Check also, if you have that option in the configuration
set protocols bgp xxxxx parameters default no-ipv4-unicast
show ipv6 bgp summary is not existing on the latest rolling, only show ip bgp summary…
Example of show ip bgp summary:
Setting set protocols bgp xxxxx parameters default no-ipv4-unicast did not have any effect.
Seems that show ipv6 bgp summary is completely missing in the latest rolling releases.
In older releases i’ve had this command available.
Hello @AWHarvard , can you check sudo dmesg output?
Can you try to increase sysctl options
configure
set system sysctl custom net.ipv6.route.max_size value 655360
set system sysctl custom net.core.wmem_max value 425984
set system sysctl custom net.core.rmem_max value 446464
commit
dmesg not showing any special also not after adjusting the settings.
What confueses me is that only show ip bgp summary and not show ipv6 bgp summary.
show ip bgp summary only shows a IPv4 summary:
It was for 1.3
For 1.4
show bgp ipv6 summary
Thanks @Viacheslav this in combination with set protocols bgp xxxxx parameters default no-ipv4-unicast solved my issue.
