I had an issue with my router vm in a cluster and had to drop it and create another one. This happened for all of my zones. I had to drop and recreate all router vms.
While my issue was addressed by redeploying a new router vm (typical DHCP, DNS and UserData offering) I'm not certain if the dhcp info for previous existing instances is preserved and carried over to a new router vm. I see that the IP information is stored in DB, however I dont know if the router vm pulls iP info from DB and recreates dhcpd leases fIle. As always - any feedback is appreciated. Thanks Ilya
