Question 1 Suppose a router has 4 links, and packets are to be forwarded as follows: Destination address range Link interface 00000000 00000000 00000000 00000000 through 0 00001111 11111111 11111111 11111111 00110000 01000000 00000000 00000000 through 1 00110000 01000111 11111111 11111111 01000011 01000000 00000000 00000000 through 2 01000011 01111111 11111111 111 111 otherwise 3 (a) Provide a forwarding table that has 4 entries. (b) Find the link interface for datagrams with the following destination addresses. 00110000 01001001 01010001 01010101 00110000 01000100 11000011 00111100 [1 mark]
