I see you are using the rfc3442-classless-static-routes option to get an IP and routes for the IPTV VLAN interface.
Currently this will not work as expected because EdgeOS is missing a script that is needed for this option to do what it is intended to do: Configure routes.
This issue can be solved by getting this script from Here, for example. You'll have to copy it to /etc/dhcp3/dhclient-exit-hooks.d/rfc3442-classless-routes and chmod it to 755.
It should do the trick (and at least it does for IPTV provided by Orange in France).
