A forwarding equivalence class is _____.
A)a new kind of address class used in large networks
B)a mechanism to treat all networks as equivalent to each other
C)a group of IP packets treated similarly in the network
D)None of the above

Question

Quizplus · Accepted Answer

A forwarding equivalence class (FEC) is a group of IP packets that are treated in a similar manner by the network. FECs are used in Multi-Protocol Label Switching (MPLS) networks for efficient packet forwarding. MPLS routers can group packets that have the same destination address, destination port, or other common characteristics into a forwarding equivalence class, which is assigned a unique identifier. This allows routers to apply similar forwarding treatments, such as priority or traffic engineering, to all packets within the FEC. Therefore, option (C) is the correct answer. Option (A) is incorrect because forwarding equivalence classes are not related to address classes. Option (B) is incorrect because FECs do not treat all networks as equivalent to each other. Option (D) is incorrect because (C) is the correct answer.
