I’m changing to the fiber.nl provider in the Netherlands soon and I would love to be able to just hook up a route10 and ap7 to the ont and change some settings, add the VLAN and call it a day. Unfortunately, the reality is a bit more complicated. My provider stated they don’t officially support taking out their own modem because they use its serial number for authentication. They do suggest that i can do something called serial number spoofing and get it working that way. Bit of a long shot but does the route 10 support this?
Your new XGS-PON network uses an ONT, a modem is no longer in the conversation. Route10 will hook up to your network providers ONT without issue and can be configured as easily as you described. Their ONT might be looking for a serial number if you’re opting out of using their supplied router, but based on what you’ve written this isn’t the case.
You may be confusing this with the current “craze” to replace network providers ONTs with an ONT on a stick setup. You can do this through the use of a WAS-110 or X-ONU-SFPP and following instructions from the 8311 community wiki. The Route10 should work with either and there are posts on the forum you can read about this setup further.
