B4. (a) Match the following terms used in DUAL algorithm for EIGRP to the appropriate description shown in Table B4: feasible condition, successor, feasible successor, reported distance and feasible distance. Packet Type (i) (ii) (iii) (iv) (v) Description This is the reported metric from the neighbour advertising the route. Satisfied when a neighbour's Reported Distance (RD) is less than the local router's feasible distance. The lowest calculated metric to reach the destination network. This is the "backup path that is loop-free. Neighbouring router with the least-cost route to the destination network. Table B4 (10 marks) (b) List down three metrics used in EIGRP composite metrics to determine the cost to reach a destination network. (3 marks) (c) What does it mean to have equal cost load balancing during routing? (2 marks) - End of Paper -
