by doing that we restrict the MinAdvertisementInterval and
MaxAdvertisementInterval for all the interface to be the same. coz the
transmission interval has to be a random value "between these min and max"
right?
for eg: on eth0 we have min = 600 and max = 800 and
on eth1 we have min = 200 and max = 500 secs.
next time out for eth0 shud be in the range 600 - 800
next time out for eth1 shud be in the range 200 - 500 ??
