Running FRR on both Primary and Backup pfSense
If possible I would like to keep FRR running on both my Primary and Backup nodes. However, this causes a problem if the LAN gateway VIP moves to Backup while Primary is still online (for instance, when enabling persistent CARP maintenance mode). Traffic in this case can get routed to the Primary but then exit the Backup node creating asymmetrical routing. I'd like to keep FRR running on both to avoid the delay in waiting for FRR to startup during a pfSense failover.
