Intro to Routing & Switching

OBJECTIVES Upon completion of this chapter, you

should be able to: Identify an IPv6 address Identify the prefix, subnet ID, and

interface IDExplain how to borrow bits Identify a subnetted IPv6 addressExplain how IPv6 address assignments are

implemented in a business network.

IPV6 REVIEW- 5Q How many bits in an IPv6 address?

128

How many hextets in an IPv6 address? 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

IPV6 REVIEW- 4Q How many bits is the interface ID?

64

What is the prefix ID?2001:db8:4a7d:1f:1234:acad:abe5:115f/482001:db8:4a7d::

What is the interface ID?1234:acad:abe5:115f

What is the 1f?Subnet ID

IPV6 SUBNETTING Why? It’s not even needed! For design only, NOT for conserving

ACTIVITY Packet Tracer Lab 9.3.1.4

Subnetting an IPv6 NetworkYour 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.

IP DESIGN SCHEME

9.2

PLAN TO ADDRESS Prevent duplicate addresses

Each host/port needs a unique IPKeep documentation

Assign static addressesServers & printers need to be accessed

They can’t have random IPs!

Monitor performanceProper planning of network (separating

subnets, making them smaller) makes for less bottlenecks

WHAT NEEDS ADDRESSES?

Name some things…

Set a pattern for each group

ADDRESSING 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 1st or last address pattern

CHALLENGE 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.
