Chapter 9 b Intro to Routing & Switching

� Upon completion of this chapter, you should be able to: �Identify an IPv 6 address �Identify the prefix, subnet ID, and interface ID �Explain how to borrow bits �Identify a subnetted IPv 6 address �Explain how IPv 6 address assignments are implemented in a business network.

� How many � 128 bits in an IPv 6 address? � How � 8 many hextets in an IPv 6 address? � How � 16 many bits in a hextet? � What are the 3 portions � Prefix, subnet, interface � How many addresses � 340 undecillion of the address? are available in IPv 6?

� How many bits is the interface ID? � 64 � What is the prefix ID? 2001: db 8: 4 a 7 d: 1 f: 1234: acad: abe 5: 115 f/48 � 2001: db 8: 4 a 7 d: : � What is the interface ID? � 1234: acad: abe 5: 115 f � What is the 1 f? �Subnet ID

� Why? It’s not even needed! � For design only, NOT for conserving addresses �Hierarchy (order)

� Borrowed bits from the interface ID � Remember: �Nibble �/68 �/72 �/76 �/80, etc. 1 hex digit is 4 bits

� Packet Tracer Lab 9. 3. 1. 4 �Subnetting an IPv 6 Network �Your network administrator wants you to assign five /64 IPv 6 subnets to the network shown in the topology. Your job is to determine the IPv 6 subnets, assign IPv 6 addresses to the routers, and set the PCs to automatically receive IPv 6 addressing. Your final step is to verify connectivity between IPv 6 hosts.

9. 2

� Prevent duplicate addresses �Each host/port needs a unique IP �Keep documentation � Assign static addresses �Servers & printers need to be accessed They can’t have random IPs! � Monitor �Proper performance planning of network (separating subnets, making them smaller) makes for less bottlenecks

� Name � Set some things… a pattern for each group

� Clients- DHCP assignment � Automatic within a set range � Leased addresses can change � Servers & Printers � Set statically for access � Servers that access � Email & web � Public IP Internet � Switches & WAPs � For management � Assigned manually � Router ports � Static � 1 st or last address pattern

� 9. 4. 1. 2 Packet Tracer �As a network technician familiar with IPv 4 and IPv 6 addressing implementations, you are now ready to take an existing network infrastructure and apply your knowledge and skills to finalize the configuration. The network administrator has already configured some commands on the routers. Do not to erase or modify those configurations. Your task is to complete the IPv 4 and IPv 6 addressing scheme, implement IPv 4 and IPv 6 addressing, and verify connectivity. � Worth 2 100 test grades!
