When setting up Frame Relay for point-to-point subinterfaces, which of...
Explanation:
Setting up Frame Relay for point-to-point subinterfaces involves configuring certain parameters to establish the connection correctly. Among the options provided, the IP address on the physical interface must not be configured for point-to-point subinterfaces. Here's why:
Detailed Explanation:
The Frame Relay encapsulation on the physical interface: This is a necessary step to ensure that the physical interface is set up to communicate using the Frame Relay protocol.
The local DLCI on each subinterface: Each subinterface should be assigned a unique DLCI (Data Link Connection Identifier) to identify the connection between the two endpoints.
An IP address on the physical interface: In the case of point-to-point subinterfaces, the IP address is configured on the subinterfaces themselves rather than the physical interface. This allows for more efficient use of IP addresses and better segregation of traffic.
The subinterface type as point-to-point: Configuring the subinterface as point-to-point is essential to define the type of connection and ensure that the communication between the two endpoints is established correctly.
In conclusion, while setting up Frame Relay for point-to-point subinterfaces, it is important to configure the Frame Relay encapsulation, local DLCI on each subinterface, and the subinterface type as point-to-point. However, the IP address should not be configured on the physical interface in this particular setup.
