Hello, further information.
The controllers where router namespace is absent have issues on openvswitch agent, this is probably the cause of br-int error.
The error in openvswitch agent log is reported here:

Thanks

Hello Everyone,
I am facing an issue with router-ha in kolla wallaby. In my neutron.conf I inserted l3_ha = True
max_l3_agents_per_router = 3
l3_ha_net_cidr = 169.254.192.0/18
but router ha does not work.
The router namespace is present only on one of the three contrllers and if the controller goes down routing stop to work.
I am using ovs and not ovn.
Any help,please ?
Ignazio
