Comment 2 for bug 2020341

Hi Michal, thanks for your reply.

According to the neutron config reference doc, l3_ha and max_l3_agents_per_router is router HA related config variables. But dhcp_agents_per_network is only related to dhcp agent HA.

l3_ha : https://docs.openstack.org/neutron/latest/configuration/neutron.html#DEFAULT.l3_ha

dhcp_agents_per_network: https://docs.openstack.org/neutron/latest/configuration/neutron.html#DEFAULT.dhcp_agents_per_network

max_l3_agents_per_router : https://docs.openstack.org/neutron/latest/configuration/neutron.html#DEFAULT.max_l3_agents_per_router

According to the RedHat docs when using DVR l3_ha is not supported: https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/16.0/html/networking_guide/sec-dvr#:~:text=DVR%20is%20not,a%20different%20node.

Our setup is dvr and we want to use the dhcp agent HA but could not use l3_ha. We have to override the l3_ha=False
