ISP ONU in bridge mode with Deco xe75 in router mode for Internet 

ISP is launching iptv with a different vlan 

the configuration sop provided by isp for route in onu details the following:

dhcp mode
vlan id(different from internet vlan)

igmp snooping

multicast vlan

static routes

is the only way to go with a route on isp onu or can I bridge or integrate it with the deco somehow?
