P5. Consider a datagram network using 32-bit host addresses. Suppose a router has four links, numbered 0 through 3, and packets are to be forwarded to the link interfaces as follows: Destination Address Range Link Interface 11100000 00000000 00000000 00000000 through 11100000 00111111 1111 11111111 11100000 01000000 00000000 00000000 through 11100000 01000000 11111111 11111111 1 11100000 01000001 00000000 00000000 through 11100001 01111111 11111111 11111111 2 otherwise a. Provide a forwarding table that has five entries, uses longest prefix match- ing, and forwards packets to the correct link interfaces. b.
