Introduction
Tutorial introduces the high level planning
p 
considerations which any network
operator needs to be aware of prior to
deploying IPv6
Content applicable for:
p 
Business decision makers
n 
Network managers
n 
Network engineers
n 
Will also require implementation detail

Goals
What do we want to achieve?
5
Goals
Ultimate aim is to provide IPv6 to our
p 
customers:
Customers = end users
n 
Customers = content providers
n 
Strategy depends on network transport:
p 
Native IP backbone
n 
Dual Stack is the solution
p 
MPLS backbone (tunnels)
n 
6PE or 6VPE is the solution
p 
The core infrastructure will remain IPv4 only
p 
6
Native IP Backbone
Routers are the infrastructure
p 
Customer connections connect to the native
n 
backbone
VPN services provided using GRE, IPSEC,
n 
IPinIP etc
Providing IPv6 for customers means upgrading
n 
the native infrastructure to dual-stack
IPv4 IPv4 IPv4 IPv4 IPv4
IPv6 IPv6 IPv6 IPv6 IPv6
7
MPLS Backbone
Routers are the infrastructure
p 
Public and Private network access provided
n 
within the MPLS cloud
The core network does NOT need to be IPv6
n 
aware
IPv6 access provided by 6PE or 6VPE
n 
Provider Edge routers need dual stack

Network Audit
What can run IPv6 today, and
what needs to be upgraded?
9
Audit
First step in any deployment:
p 
Audit existing network infrastructure
n 
Primarily routers across backbone
p 
Perhaps also critical servers and services (but
n 
not essential as initial focus is on routing
infrastructure)
