Dual Stack in a Virtual Data Center Environment

What is Dual Stack

Dual stack simply means configuring an IPv4 address and an IPv6 address on the same interface of a particular device (Router,L3 switch).

This means you do not need separate physical or virtual interfaces to configure both an IPv4 and IPv6 address. In fact you do not need a separate VLAN for an IPv6 address, it will be configured within the same VLAN as the IPv4 address.

This is probably the best option for an enterprise that already has a IPv4 environment and now want to embark on IPv6 infrastructure.

Which is exactly what I have done for my IPv6 deployment for an Enterprise Virtual Data Center.

To configure IPv6 you simply enter the correct commands, starting with IPv6 unicast routing........

The diagram below provide a bit more of a clear understanding on the subject.

IPv6 - What do you do with all those 000000...... Coming from a IPv4 background and training, when you first look at a IPv6 address, it seems quite scary. When you couple that IPv6 address with a horrendous amount of zero's, it becomes very scary. The full length address format looks like this: 200B:AA00: 0 200: 0000:0000:0000:0000:0000:0000 /48 The 200B:AA00:200:: /48 There are two things to notice from comparing the full length format to the compressed format. In the compressed format, the trailing zeros have been omitted from the full length address, this tells you, from the 4 th to 8 th hextect, they are all 0’s. Any preceding 0’s can be omitted from the long format version, as you can see from full length format, 0200 becomes 200 in the compressed format. Network                                 ...

IPv6 Overview There are a number of ways an Enterprise can deploy IPv6 within in their organization, the three main types are as follows; the brief list below, highlights the three types. ·          Dual Stack Mode (DSM) – End-to-end dual stack network ·          Hybrid Model-Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) and dual-stack ·          Service Based Model (SBM) Combination of ISATAP, manually-configured tunnels and dual-stack DSM is completely based on the dual-stack transition mechanism. A device or network on which two protocol stacks have been enabled at the same time operates in dual-stack mode. This means on routers, L3 switches, Firewalls etc. can have an IPv4 and an IPv6 address co-existing on the same interface. Dual-stack is the preferred, most versatile way to deploy IPv6 in existing IPv4 environments...
