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.


How many bits in an IPv6 address?


How many hextets in an IPv6 address?



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

1234:acad:abe5:115f
 What

is the interface ID?
is the 1f?
Subnet ID
 Why?
It’s not even needed!
 For design only, NOT for conserving addresses

Hierarchy (order)
 Borrowed
bits from the interface ID
 Remember:

/72
/76
/80, etc.

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


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

duplicate addresses
performance
Proper planning of network (separating subnets,
making them smaller) makes for less bottlenecks
 Name
 Set
some things…
a pattern for each group



Set statically for access
Servers that access Internet


Automatic within a set range
Leased addresses can change

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.
