Title: BGP Dead after upgrade to 20.7 (Solved)
Post by: xoclutch on August 02, 2020, 11:48:39 AM
After upgrading to the latest (20.7) BGP refuses to transfer routes.  It connects, shows established, says its transferring routes, but nothing is actually being transferred, nothing appearing in logs.

Just Broke.  This is occurring with both Opnsense to Cisco Switch, and Opnsense to Mikrotik router.  Everything works fines with other versions.

Trying to find log information, but nothing seems to be appearing in the logs related to the issue.

Hi,

I was about to upgrade 2 of my firewalls that have FRR for BGP. So Iĺl wait a bit.

Could you use the CLI to run vtysh which is the cli tool for frr and enable debug and see if frr is reporting anything directly?

Also can you share output (from within vtysh) of show bgp neighbours and show ip bgp statistics

Thanks,

Alex

sh run would also be nice, and also logs when restarting FRR.
The version of FRR was updated from 6 to 7

It seems FRR 7.4 is broken with FreeBSD.

@xoclutch .. if you cant revert you can load the 7.3 from RC1 which worked for me:

fetch https://pkg.opnsense.org/FreeBSD:12:amd64/20.7/MINT/20.7.r1/OpenSSL/All/frr7-7.3.1.txz
pkg install frr7-7.3.1.txz

# opnsense-revert -r 20.1.r1 frr7

Should work as well in that case to get people up and running...


Cheers,
Franco

Before next release (say 20.7.1), do we need un-revert for the system to upgrade?

Basically what should be done once the official fix is in place and one had used the opnsense-revert command?

Nothing, it will upgrade from 7.3 to 7.4 and disable requirement for ebgp policies
