IPv6 RA always contains an implicit default route via

the guest to install a route via isolated network, which
may disturb the guest's networking in case of multiple interfaces.
More info in 013427e6e733f7a662f4e8a9c11f7dad4cd65e3f.
The validity of this route is controlled by "default [route] lifetime"
field of RA. If the lifetime is set to 0 seconds, then no route
is installed by receiver.
dnsmasq 2.67+ supports "ra-param=<interface>,<RA interval>,<default
lifetime>" option. We pass "ra-param=*,0,0"
(here, RA_interval=0 means default) to disable default gateway in RA
for isolated networks.
ACK (assuming that you've run make syntax-check and make check.)
Thanks again for spending the time to investigate this!
