IPv6 (Cisco) Training - Using the "DNS server and the domain name (IPv6)" Commands

Now that this article is a kind of long I'll be up to him to this point without further ado let us begin.

"DNS Server" (IPv6) command is a Cisco IOS "DHCP for IPv6 pool configuration command mode is a network accessible to specify the Domain Name System (DNS) server IPv6 (n).

Here is the correct syntax and example of the "DNS-server" (IPv6) command:

Syntax: Router (config-dhcp) # DNS server IPv6 address
Example:Router (config-dhcp) # dns-server 2001:0 DC8: 3000:3000:: 42

Note that the router asks for the DHCP pool configuration "mode and the argument is the IPv6 address IPv6 IPv6 address of the DNS server available.

Now, in case you were wondering, it is possible (configuration) of the "dns-server" (IPv6), the command multiple times on a router, network, if you have multiple DNS servers on your computer. And, the new IPv6 addresses, do not delete (overwrite) the existing (pre-) ipv6Addresses.

Although you must list server to remove a specific DNS server for DNS, all you have to do what the command is the word "no" before as you can see below:

Syntax: Router (config-dhcp) # no DNS server IPv6 address
Example: Router (config-dhcp) # no DNS server 2001:0 DC8: 3000:3000:: 42

Ok, that pretty much sums up the "DNS-server" (IPv6) command, so let's continue with the command "domain" name (IPv6).

The "domain name" (IPv6)Command is also a Cisco IOS "DHCP for IPv6 pool configuration" mode command, but is used to configure domain name RR for a DHCP client for IPv6, router, or is also known as a request.

Here is the correct syntax and example for the domain name "(IPv6) command:

Syntax: Router (config-dhcp) # domain-name domain
Example: Router (config-dhcp) # domain-name ittechtips.com

Note that the router is ready again to DHCP for IPv6 pool configuration mode and the subject domain is an indication of the domain name to be used by the client. So in the above example the router (client) ittechtips.com use of the domain name.

And just like the "DNS-server" (IPv6) command, the domain name "(IPv6) command can be used (configuration) repeatedly to be a router. And the new domain names do not delete (overwrite) existing domain name.

Finally, if you need to remove a domain name to a DHCPv6> Client (RR), you need the word "no" in front of the domain name "(IPv6) command as you can see below:

Syntax: Router (config-dhcp) # domain without domain name
Example: Router (config-dhcp) # no domain name ittechtips.com

I hope this article was very informative and helped you quickly understand the use of the DNS server and the domain name "(IPv6) command. To learn more, I suggest you visit my website, where you will find the latest informationCisco IPv6 Design and implementation techniques.
