6. An organization is assigned the following address space: 170.88.22.0/23. This space is divided as follows: N4 and N5 get assigned 170.88.22.0/25 and 170.88.22.128/25, respectively. N1 needs more capacity than N2 and N3. (a) Assign network IDs for N1, N2 and N3. State how many hosts can be allocated in each subnetwork with your choice. (b) Write the routing tables for R1 in CIDR format (example: x.x.x.x/xx L1). Include the default route (and reject routes if needed). (c) Find the destination network for a packet coming to R1 from L8 with destination address 170.88.23.143. Show which routing table entry is matched in R1. N1 L1 L6 R1 L8 to Internet L7 N2 L2 R2 22 L3 L4 23 R3 L5 N3 N4 N5
