Parser View

With CLI view, we can restrict which access each network administrator have based on role.Superviews allow a network administrator to easily assign all users within configured CLI views to a superview instead of having to assign multiple CLI views to a group of users. 


Here is the basic configuration of the Parser View.


R2 <----> R3    
192.168.1.1   <---->  192.168.1.2


Task: 

• Allowing telnet access with the username OPERATOR and password CISCO to be able to configure the HTTP feature in the router only.
• Configure Username ADMIN and password CISCO to have access to every feature in the router.

Cisco IOS NAT on a Stick Configuration Example

NAT (Network Address Translation) is most commonly used to let users on our LAN access the Internet using a single public IP address but it can be used for some more interesting scenarios. Recently I encountered an interesting CCIE R&S task that had the following requirement:

"Make sure that whenever R2 responds to a traceroute it replies with the IP address on the loopback 0 interface"

This sounds easy enough but there’s no such thing as a “traceroute source loopback 0″ command or anything alike. To make this work we have to configure the NAT on a stick feature. In this tutorial I’ll show you this is done. First of all, this is the topology that we will use:

There are only two routers that are directly connected to each other. R2 has a loopback 0 interface with IP address 2.2.2.0 /24. Let’s configure these IP addresses first:
