What is the impact of IPv6 routers on Network Management?

As one of the most popular technologies in network applications, IPv6 routers play an important role in it. Here we mainly analyze the impact of IPv6 routers on network management, I hope you will gain some benefits after reading this article. Significant changes in the IPv6 Router Protocol improve network device management.

First, adding an IP address from 32-bit to 128-bit will increase the structure and allocation of the IP address. An IPv6 address consists of a global route prefix, a subnet ID, and an interface ID (local link in the LAN ). The unique parts of the address domain are distributed hierarchically according to the network infrastructure Topology Defined by the Internet address distribution Agency (IANA. This will make the global route table of the IPv6 router very small, thus avoiding some scaling problems encountered by the BGP Route.

Second, IPv6 routers have enough addresses to assign a unique IP address to each square inch of the Earth. Although this can actually assign an IP address to any device you can think of, it is a nightmare for the administrator who manages the address allocation. Fortunately, the IPv6 router provides the "Automatic node configuration" function. This is actually the next generation technology that replaces DHCP (Dynamic Host Configuration Protocol) and ARP (Address Resolution Protocol) in all IPv6 router networks, this allows you to connect new devices to the network without any configuration. If you change the ISP (so you are assigned a different global route prefix), this function makes it easier to reassign IP addresses to your network, because all you have to do is change the configuration of your vro, and your network will get a new address with a new prefix. This will reduce the huge burden on network management.

With the increase of IPv6 router functions, some potential management problems have emerged. The IPv6 router provides security support, which is called "IPsec ". Based on the VPN method, encryption may include header information that may not be included. VPN can reduce the workload of communication management between the client and the server. The security policies between management endpoints (IKE, Internet Key Exchange) are also complex, if you want to do this yourself. This is one of the main functions provided by IPsec and VPN. Of course, IPsec can be very powerful, but in some cases remote access is very fragile, for example, using a mobile device to access an enterprise network. The provision of such services by the IT Department will further increase the management burden.

There is no need to take a big step to complete the transition from the current IPv4 network to the IPv6 Router Network, because the new technology provides the gateway service between the two networks, for example, the BIG-IP IPv6 gateway produced by F5 network company. The BIG-IP provides a full proxy for communications between an IPv4 network and an IPv6 Router Network, allowing all communications to be converted to IPv4 or communication that can be processed by IPv6 endpoints. This will allow organizations to gradually transition to IPv6.
