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

37

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.

Can addresses on the same network segment be configured on different interfaces of an AR
Addresses on the same network segment cannot be allocated to interfaces on an AR. Interfaces on an AR can be configured with IP addresses on network segments that overlap. For example, an interface is assigned IP address 20.1.1.1/16. When you configure IP address 20.1.1.2/24 for the other interface, the system displays a message. However, the configuration is successful. When you configure IP address 20.1.1.2/16 for the other interface, the system displays a message indicating that the address conflicts. The configuration fails. The primary and secondary addresses of an interface can be on network segments that overlap, but must be different. For example, an interface is configured with the primary IP address 20.1.1.1/24. When you configure the secondary IP address 20.1.1.2/16, the system displays a message. However, the configuration is successful. The primary and secondary addresses of interfaces can be on network segments that overlap, but must be different. For example, an interface is configured with IP address 20.1.1.1/16. When you configure IP address 20.1.1.2/24, the system displays a message. However, the configuration is successful.

Are the supply voltages of the FXS interfaces on AR routers the same
The supply voltages of the FXS interfaces on different AR routers may not be the same.

Can the LAC address and LNS VT interface address be on different segments on the AR
The LAC address and LNS VT interface address can be on different segments on the AR. The LAC can communicate with the LNS, but you are not advised to configure different network segments for them.

Are My BMSs in the Same Subnet?

You can customize your networks. Therefore, no matter your BMSs use the common network or high-speed network, you can control whether they are in the same subnet.
