Routed IPv6 prefix in 6in4 WAN connectivity is not marked as mandatory but required to be filled in
While setting up the 6in4 connectivity, I have found that I cannot save the configuration unless the
Routed IPv6 prefix is specified. According the UCI network cheatsheet, the value is not mandatory, but as we do not offer the ability to specify the IPv6 address of the local end of the tunnel, the
Routed IPv6 prefix should be marked as mandatory.
