[PVE-User] OSPF when migrating from v8 to v9

[Julien OHAYON]

Hello,

We are running version 8.4.1 and using SDN with EVPN. Since we already had OSPF in our infrastructure, we forced its activation through the configuration files and added some local configs. A few examples:

in /etc/frr/daemons

ospfd=yes
and
in /etc/frr/frr.conf.local

router ospf
 redistribute connected
 redistribute static
 network X.X.X.X/24 area 0
 default-information originate
exit

However, with version 9, great news: it is now integrated. But for the migration, it’s not so simple. When we upgrade a node to v9, OSPF gets disabled in /etc/frr/daemons.

Is it possible to keep it enabled? If yes, in which configuration file?

Of course, afterwards it will be fine to modify the configuration via Proxmox, but what is the impact, especially if it doesn’t match the configuration we had manually applied?

Thanks in advance.
