I have a bug with features that require you to choose a device by the device's name and IP address, such as hybrid VPN, internet rules, etc. If the device has a local link address, this takes priority over the private IP address, resulting in the features not working on the device.
Additionally, is a device supposed to have that many IPv6 addresses?
Edit: Restarting the R3 has fixed the issue by removing the local link address and reducing the IPv6 addresses to two.
