IPv6 Training Cisco Enabling SSH on a Cisco IPv6 Router

Secure Shell or SSH is an Application layer convention that utilizes a protected channel; the safe channel guarantees that the information being traded between two IP gadgets is absolutely secure encoded.  A Cisco IPv6 switch can either act like a SSH worker or a SSH customer. At the point when a Cisco IPv6 switch is acting like a SSH worker, it permits a SSH customer IP gadget to make a safe, encoded association with the Cisco switch; and when a Cisco IPv6 switch is acting like a SSH customer, it can make a protected, scrambled association with another Cisco switch or to some other IP gadget running as a SSH worker.

Presently, before you can empower Secure Shell or SSH on a Cisco IPv6 switch, the switch should meet certain prerequisites and those necessities are:

  • The switch should be imaged with either an IPsec Data Encryption Standard DES or a Triple Data Encryption Standard 3DES encryption programming picture.
  • It ought to be running Cisco IOS Release 12.13T or higher.
  • It ought to be designed with a host name by utilizing the SSH Client arrangement order hostname and a host space by utilizing the worldwide setup order ip area name.
  • It should as of now have a Rivest, Shamir, and Adelman RSA key pair produced. The RSA key pair is utilized to consequently empower SSH on the switch; to produce a RSA key pair utilize the crypto key create rsa worldwide arrangement order.
  • It should as of now have a client verification component designed for nearby or distant access. Presently, with SSH over an IPv6 transport; the lone client confirmation component upheld is privately put away usernames and passwords. The TACACS+ and RADIUS client confirmation systems are not upheld over an IPv6 transport. In any case, in the event that you are in an IPv6 network climate and might want to have either TACACS+ or RADIUS validate SSH customers; you should arrange TACACS+ or RADIUS over an IPv4 move and afterward interface with a SSH worker over an IPv6 transport.

Here are the means to empower SSH worker on an IPv6 switch:

  1. Router>enable
  2. Router#configure terminal
  3. Routerconfig#ip Ssh [timeout seconds | validation retries integer]
  4. Routerconfig#exit
  5. Router#copy runs start

Step #1

  1. Router>enable

Places switch into Privileged EXEC mode.

Step #2

  1. Router#configure terminal

Places switch into Global arrangement mode.

Step #3

  1. Routerconfig#ip Ssh break 100 validation retries 2

Designs the SSH worker control factors on the switch.

Step #4

  1. Routerconfig#exit

Makes switch exit worldwide arrangement mode and reenters into Privileged EXEC mode.

Step #5

  1. Router#copy runs start

Recoveries the substance of the running-config to nearby Non – Volatile Random Access Memory NVRAM

The following are the means that permit a Cisco IPv6 switch that is acting like a SSH customer to start an encoded SSH meeting with a distant systems administration gadget.
