Route internet traffic based on NBAR via different ISPs

Hi, I have a question if anyone have a good solution to a small issue:

In the setup there are 2 ISPs with different paths to sites, and I want to send out default internet traffic on 1 ISP, that is no problem, but I want some specific categories/sites ( like Youtube / google ) to exit on ISP2 as it has better access to those sites. ( yes they are blocked by ISP 1 ).

I would love if there was internet routes based on NBAR so I could point out what WAN interface to exit the traffic on...
( eg. next hop for [....]  via interface (dropdownlist) )

Any ideas how to solve it until meraki implements it 😉

In theory it's a piece of cake:

 

  1. Find feeds for the prefixes that are being used by those services
  2. Parse them and feed them into your Dashboard using the API

The hard part could be getting your hands on the needed prefixes though...

I did a quick Google, and it looks like YouTube uses these IP address blocks:

  • 199.223.232.0 - 199.223.239.255
  • 207.223.160.0 - 207.223.175.255
  • 208.65.152.0 - 208.65.155.255
  • 208.117.224.0 - 208.117.255.255
  • 209.85.128.0 - 209.85.255.255
  • 216.58.192.0 - 216.58.223.255
  • 216.239.32.0 - 216.239.63.255

You'll need to specify a flow preference for them via WAN2.

Hi, thx for that, I also looke up the different AS numbers that facebook and google uses and listed al the networks there, and came to the conclusion together with the end user that we will buy that as a service from the ISP that uses a different product for now. As soon as the Dashboard gets those functions we will use that function in Meraki.
