FRR/BGP Sessions restarting when disabling an interface - pfSense 2.7.2

[dudumiquim]

I'm experiencing an unexpected behavior in my setup:

• 3 gateways
• 6 BGP sessions over VTI
• pfSense 2.7.2-RELEASE (amd64)

When I disable an interface connected to my ISP, all BGP sessions restart. The same happens if my ISP goes down. My expectation is that only the sessions over the affected ISP should go down, while the others remain stable.

Here’s an example from the logs when I disable the ETH1 interface:

Feb 13 11:14:44	php-fpm	90326	/interfaces.php: Forcefully reloading IPsec
Feb 13 11:14:43	snmpd	97722	disk_OS_get_disks: adding device 'ada0' to device list
Feb 13 11:14:43	php-fpm	90326	/interfaces.php: Resyncing OpenVPN instances for interface ETH1.
Feb 13 11:14:43	check_reload_status	429	Reloading filter
Feb 13 11:14:43	check_reload_status	429	Restarting OpenVPN tunnels/interfaces
Feb 13 11:14:43	check_reload_status	429	Restarting IPsec tunnels

Has anyone encountered this issue? Is there a way to prevent all BGP sessions from restarting when only one ISP goes down?

Thanks in advance!

I first reported the issue. There is a redmine.

• Disable Gateway Monitoring Actions for your WAN. That somewhat solves one issue but there is instability with Ipsec and FRR
