[neutron] neutron l3 agents number

Hey team,

When using DVR + HA, we endup with all routers beeing deployed on the computes (the DVR part) and 3 routers on dvr_snat nodes (for HA).

The question is why 3 for snats? I know that this is the max_l3_agents_per_router config parameter, but 2 seems enough?

On the other side, DHCP agent default (dhcp_agents_per_network) is 1, while this is also a precious service provided in the tenant network.

So, is there any downside on having only 2 agents for routers?

Thanks in advance,

Arnaud.
