NET 413 Homework #3 Due Saturday Oct 23, 2021, by 11:59 pm 100 points total 1. (10 points) A DHCP Server allocates each IPv4 address with a lease time. What is the purpose of the lease time? What happens if an IPv4 client does not renew its IPv4 address before the lease time expires? 2. (10 points) Write out the IPv6 address 2001:6A:112:2BB::69:C in binary. Your answer must contain 128 bit values – each bit value being ‘0’ or ‘1’. 3. (10 points) My workstation has a single Ethernet interface with MAC address 00:AB:99:51:C3:22. What is the IPv6 Link-Local Address for this interface, assuming my workstation uses the EUI-64 standard to determine its Interface Identifier? 4. (10 points) IPv6 does not use the ARP protocol. What protocol provides ARP functionality on an IPv6 network? What IPv6 Table serves the same purpose as the IPv4 ARP table for IPv6 hosts? 5. When an IPv6 device with no pre-configured IPv6 address powers up, it can calculate a global 128-bit IPv6 address for itself using Stateless Address Autoconfiguration (SLAAC), which combines two values: (a) a 64-bit IPv6 Prefix for the subnet (link) and (b) a 64-bit Interface ID. a) (10points) How does the device learn the value of the IPv6 Prefix for its subnet? b) (10 points) How does the device determine the value of its Interface ID? Describe 2 ways. c) (10 points) what are the EtherChannel limitations? d) (10 points) List the steps to configure EtherChannel/Port channel? 6. (20 points) Consider a router that has the following Routing Table contents. For parts (a) – (d), answer with “Fa0/0”, “Fa0/1” or “Fa0/2”. Destination Subnet Outgoing Interface Next Hop 99.111.30.32/27 Fa0/0 118.2.77.4 99.111.16.0/20 Fa0/1 59.16.1.1 0.0.0.0/0 Fa0/2 18.12.52.43 a) A packet with destination IP address 99.111.30.70 arrives to this router. Out what interface will this packet be sent? b) A packet with destination IP address 99.111.30.60 arrives to this router. Out what interface will this packet be sent? c) A packet with destination IP address 99.111.32.5 arrives to this router. Out what interface will this packet be sent? d) A packet with destination IP address 99.111.30.34 arrives to this router. Out what interface will this packet be sent? NET 413 HW 31

1. The purpose of lease time is to free IPs allocated to machines that are no longer connected to the system. The DHCP server maintains the record of each IP allocated against the Machine’s MAC (physical) address. When a machine is disconnected from the network, there is no way for DHCP server to know this. Thus the DHCP server allocates every IP for a certain lease period only and when the lease expires, the IP is renewed if the system is online at the time of renewal or else it is added back into the DHCP pool for re-allocation to other machines. If a client does not renew its lease before expiry, the IP is allocated to the next requesting client and thus when this client reconnects, it will be allocated another IP.
2. The IPv6 address in elongated form is...
