just curious, this setting does not exist in VR of isolated networks as well

root@r-1171-VM:~# grep -r dnsmasq.leases /etc/dnsmasq*
/etc/dnsmasq.conf:#dhcp-leasefile=/var/lib/misc/dnsmasq.leases
/etc/dnsmasq.conf.tmpl:#dhcp-leasefile=/var/lib/misc/dnsmasq.leases

Does the issue exist with redundant VRs of isolated network as well ?

maybe not needed, as redundant VRs are not supported

no, but the script is not only for redundant VRs. I'd like to give it a bash anyway.

so to specify, it does not fail for shared networks, it fails for redundant isolated networks.
