Chapter 9b Intro to Routing & Switching

 Upon completion of this chapter, you should be able to:  Identify an IPv6 address  Identify the prefix, subnet ID, and interface ID  Explain how to borrow bits  Identify a subnetted IPv6 address  Explain how IPv6 address assignments are implemented in a business network.

9.3

 How many bits in an IPv6 address?  128  How many hextets in an IPv6 address? 88  How many bits in a hextet?  16  What are the 3 portions of the address?  Prefix, subnet, interface  How many addresses are available in IPv6?  340 undecillion

 How many bits is the interface ID?  64  What is the prefix ID? 2001:db8:4a7d:1f:1234:acad:abe5:115f/48  2001:db8:4a7d::  What is the interface ID?  1234:acad:abe5:115f  What is the 1f?  Subnet ID

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

1st 2nd 3rd

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

 Packet Tracer Lab 9.3.1.4  Subnetting an IPv6 Network  Your network administrator wants you to assign five /64 IPv6 subnets to the network shown in the topology. Your job is to determine the IPv6 subnets, assign IPv6 addresses to the routers, and set the PCs to automatically receive IPv6 addressing. Your final step is to verify connectivity between IPv6 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 performance  Proper planning of network (separating subnets, making them smaller) makes for less bottlenecks

 Name some things…  Set 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 Internet  Email & web  Public IP  Switches & WAPs  For management  Assigned manually  Router ports  Static  1 st or last address pattern

 VLSM Lab  9.2.1.4 Paper  or  9.2.1.5 Packet Tracer VLSM Lab

 9.4.1.2 Packet Tracer  As a network technician familiar with IPv4 and IPv6 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 IPv4 and IPv6 addressing scheme, implement IPv4 and IPv6 addressing, and verify connectivity.  Worth 2 100 test grades!
