IPv6 Training (Cisco) Enabling Telnet on an IPv6 router and Telnet configuration

Well, if you do not know the word "telnet" telnet is an application layer protocol that allows direct connections (with telnet sessions), can do to a Cisco router or a Cisco router. It does not matter if you use the IPv4 or the IPv6 protocol, "telnet", leads the same way.

A network administrator can "telnet" to make the following types of direct connections (telnet sessions):


To accommodateRouter
Router to router
Router-to-Host

This article will show you how to enable "telnet" IPv6 on a Cisco router, so as to be able to connect directly via telnet sessions with him, and I also show how you can initiate a "telnet" session from a Cisco router IPv6.

Here are the steps needed to "telnet" to enable IPv6 on a Cisco router:

1 Router> enable
2 Router # configure terminal
3 Router (config) # IPv6 host name [port] ipv6-address1 [ipv6-address2 ... ipv6-address4]
4 Router (config) # line [aux | console | tty | vty] line number [ending-line-number]
5 Router (config-line) # password password
6 Router (config-line) # login [local | TACACS]
7 Router (config-line) # ipv6 ipv6-access-class access-list-name {in | out}
8 Router (config-line) # end
9 Router # copy run start

And here are the steps needed to start a session "telnet" from a > Cisco IPv6 router:

1 Router> enable
2 Router # telnet host [port] [keyword]

First Steps Explained
 
Step # 1
 
1 Router> enable

Puts the router in privileged EXEC mode.

Step # 2

2 Router # configure terminal

Puts the router in global configuration mode.

Step # 3

3 Router (config) # IPv6-Host> Cisco Test 2001:0 DB8: 20:01:: 12

Defines a static hostname to IP address mapping in the cache host name.

Step # 4
 
4 Router (config) # line vty 0 4

Create an interface and router vty line configuration mode.

Step # 5
 
5 Router (config-line) # password ittechtips

Create one (ittechtips) forgets that allows Telnet.

Step# 6

6 Router (config-line) # login TACACS

Tell the router to the server TACACS password checking at login use.

Step # 7
 
7 Router (config-line) # access-class vty in ipv6-acl

Adds an IPv6 access list named acl-vty interface, remote access to Telnet sessions that limits the access list match.

Step # 8
 
8Router (config-line) # end

The causes of the router configuration mode and get back in line to exit privileged EXEC mode.

Step # 9
 
9 Router # copy run start

Save the running-config to local Non-volatile random access memory (NVRAM).

Steps second Explained

Step # 1
 
1 Router> enable

Puts router Privileged EXECMode.

Step # 2
 
2 # telnet cisco-router tests

The command "telnet" to a Telnet session from the router to a remote host, build, or through the host name or IPv6 host address. A Telnet session can be set to the name of a router or an IPv6 address.
