Hi Friend,

You can configure an extended access list with the sourec and destination ip whch you want to restrict and apply it on line vty as access-class command

I would apply the access list directly to the vty interface, as then you can use a standard or extended access list. Doing this also means that you will not slow down all traffic passing through your router(unless it's actualy a telnet to the router it's self), as acls contribute to the delay on EVERY packet they are applied to.
