SSH to router, then able to telnet to the next routers

fsebera

I have setup my routers to allow only SSH (not telnet) access.

This is my setup

ip ssh time-out 120

ip ssh authentication-retries 3

!

!

!

line vty 0 4

login authentication LETmeIN

transport preferred ssh

transport input ssh

I am only able to SSH to any router, but once I login to the first router, I am then able to telnet (no SSH) to all other routers. Am I really using SSH protocol from the 1st router to the other routers OR did I misconfigure something?

Please help!!!

Tks

You are probably telnetting in the clear from the first router to the others. Use SSH to got the other routers directly.
