Well, just in case you are new to the word “telnet”; telnet is an Application Layer protocol that can be used to make direct connections (using telnet sessions) to a Cisco router or from a Cisco router. It doesn’t matter whether you’re using the IPv4 protocol or the IPv6 protocol, “telnet” performs in the same manner.
A network administrator can use “telnet” to make the following different types of direct connections (telnet sessions):
Host to Router
Router to Router
Router to Host
In this article, I’m going to show you how to enable “telnet” on a Cisco IPv6 router, so you’ll be able to directly connect to it via telnet sessions and I’m also going to show you how you can initiate a “telnet” session from a Cisco IPv6 Router.
Here are the steps needed to enable “telnet” on a Cisco IPv6 router:
Defines a static host name-to-address mapping in the host name cache.
Step #4
4. Router(config)#line vty 0 4
Creates a vty interface and places router into Line configuration mode.
Step #5
5. Router(config-line)#password ittechtips
Creates a (ittechtips) password that enables Telnet.
Step #6
6. Router(config-line)#login tacacs
Informs the router to use the tacacs server for password checking at login.
Step #7
7. Router(config-line)#ipv6 access-class vty-acl in
Adds an IPv6 access list named vty-acl to the line interface, which restricts remote access to telnet sessions that match the access list.
Step #8
8. Router(config-line)#end
Causes router to exit Line configuration mode and re-enters into Privileged EXEC mode.
Step #9
9. Router#copy run start
Saves the contents of the running-config to local Non -Volatile Random Access Memory (NVRAM).
Second Steps Explained:
Step #1
1. Router>enable
Puts router into Privileged EXEC mode.
Step #2
2. Router#telnet cisco-test
Using the “Telnet” command to establish a Telnet session from the router to a remote host; using either the host’s name or the host’s IPv6 address. A Telnet session can be established to a router’s name or to an IPv6 address.
