That should not be necessary. The DNS server in the router is a forwarder:
1. If the target of the DNS resolve is for a VM it has served DHCP to, it
responds with the entry
2. If not, it forwards it to the 'zone' dns server.

Or, you can set use.external.dns to 'true', restart the management server
and restart (from the api/ui) the virtual router.
But if you do, you won't get #1.
