Advantages of Configuring IS-IS Dual Stacking of IPv4 and IPv6 Unicast Addresses
If you are a service provider, you always need to add more addresses to your network. Because the IPv4 addresses have all been allocated, you need a way to add IPv6 addresses while maintaining your investment in the IPv4 infrastructure.
Dual stacking offers a way to configure both IPv6 and IPv4 simultaneously. This allows you to continue to add more subscribers even after you run out of IPv4 addresses. If you are a service provider, dual stacking can help you reduce your operational expenses and increase your capital.
Dual stacking helps to protect the investment in your existing infrastructure, the devices that support IPv4. It also allows you to add new subscribers that are using IPv6- enabled devices.
Dual stacking allows you to have more subscribers on your network, and make use of your IPv4 systems without having a lot of replacement costs. Going forward, you can purchase devices that only support IPv6.
If you are a service provider, you can expand your service offerings to customers using IPv6 and still accommodate dual addressing. You will be able to support more subscribers on your network with less work.
Devices that support dual stacking enable your business to grow because you can offer expanded services that allow you to generate more revenue.
