Model: ER7212PC  
Hardware Version: V1
Firmware Version: 5.4.20

I recently configured a ER7212PC router. My site has 3 interconnected LAN. 

 

I added 2 static routes to the router and they are working fine.

 

Unfortunately, the DHCP server running on the router does not seem to advertise those routes to the clients. When pinging on of the hosts on an adjacent LAN I get a bunch of warning about "Redirect Host" which indicates wasted bandwidth. I see nowhere on the interface to configure DHCP option 121.

 

This is a so-called "Business" product. Surely DHCP option 121 must be available. How do I set it up?

Hi @frawau 

Thanks for posting in our business forum.

We cannot add all DHCP options to the router. We don't know what is needed in your LAN. So, we offer you the custom DHCP option.

If you don't find this feature in your LAN settings, that may be because the firmware has not added it yet. Please wait for the future firmware release.

Thanks for the answer. I did not realize I had to update the firmware as the Upgrade button seemed to have no effect.

 

After update I could setup Option 121 with an "hex array" and things are working. Thanks
