Can the same subnet address be configured on different interfaces of the AR

The same subnet address cannot be configured on different interfaces of the AR.
Different interfaces on the AR can be configured with IP addresses of which the network segments overlap. For example, after an interface is assigned the IP address 20.1.1.1/16, if you configure the IP address 20.1.1.2/24 for another interface, the system displays a message. The configuration, however, is still successful. If you configure the IP address 20.1.1.2/16 for another interface, the system displays a message about an IP address conflict and the configuration fails.
The primary and secondary IP addresses of an interface can be located on overlapping network segments but not the same network segment. For example, after configuring the primary IP address 20.1.1.1/24 for an interface, if you configure the IP address 20.1.1.2/16 as the secondary IP address, the system displays a message. The configuration, however, is still successful.
Different interfaces on the same device can be configured with primary and secondary IP addresses that have overlapped network segments. For example, after configuring the IP address 20.1.1.1/16 for an interface on a device, if you configure the IP address 20.1.1.2/24 for another interface, the system displays a message. The configuration, however, is still successful.
