FRR doesn't follow CARP after 2.5.0 upgrade
Upgraded a HA pair from 2.4.5p1 to 2.5.0
FRR 0.6.4_2 to 1.1.0_8
After the upgrade, when I disable the CARP interface on the primary, FRR no longer stops on the primary, and the secondary doesn't start. Both are configured to watch a CARP interface.
If I stop FRR on the primary, then start FRR on the secondary and it starts. Moving CARP back to primary, secondary continues to run FRR until I manually stop it, and start FRR up on the primary.
