Comment 4 for bug 1843557

The only reason to have a router is to have something provide the IPv6 Router Advertisements. It is not used for anything else and no traffic will ever traverse it.

It will probably be fine to have the charm create a non-distributed router by default.

I would prefer SLAAC over DHCPv6 as it gives the units a predictable and traceable address calculated from the MAC address of the unit.

The gate test for the Octavia charm is currently using a DVR setup with multiple application instances for neutron-openvswitch, so it should be easy to validate any changes.

FWIW; I have never seen the lb-mgmt router being scheduled to one of the Octavia hosts in the gate test, but I do believe you when you say this may happen.

Bugs and patches accepted :)
