CCNA Success Secrets

There has never been a CCNA Guide like this.

Success Secrets is not about the ins and outs of CCNA. In-stead, it answers the top questions that we are asked and those we come

across in forums, our consultancy and education programs.

It tells you exactly how to deal with those questions, with tips that have never before been offered in print.

This book is also not about CCNA’s best practice and standards details. Instead, it introduces everything you want to know to be

successful with CCNA.

Free Cisco CCNA, CCNP, CCENT Tuto-rial on Switching, Spanning-Tree Proto-col (STP)

By M Aslam

A Layer 2 switch, which functions as a transparent bridge, offers no additional links for redundancy purposes. To add redundancy, a second switch must be added. Now two switches offer the transparent bridging function in parallel. LAN designs with redundant links introduce the possibility that frames might loop around the network forever. These looping frames would cause network performance problems.

For example, when the switches receive an unknown unicast, both will flood the frame out all their available ports, includ-ing the ports that link to the other switch, resulting in what is known as a bridging loop, as the frame is forwarded around and around between two switches. This occurs because parallel switches are unaware of each other. The Spanning-Tree Protocol (STP), which allows the redundant LAN links to be used while preventing frames from looping around the LAN indefinitely through those redundant links, was devel-oped to overcome the possibility of bridging loops. It enables switches to become aware of each other so that they can negotiate a loop-free path through the network. Loops are discovered before they are opened for use, and redundant links are shut down to prevent the loops from forming. STP is communicated between all connected switches on a net-

Page 18: cisco

work. Each switch executes the Spanning-Tree Algorithm (STA) based on information received from other neighboring

switches. The algorithm chooses a reference point in the network and calculates all the redundant paths to that refer-ence point. When redundant paths are found, STA picks one path to forward frames with and disables or blocks forward-ing on the other redundant paths.

STP computes a tree structure that spans all switches in a subnet or network. Redundant paths are placed in a blocking or standby state to prevent frame forwarding. The switched network is then in a loop-free condition. However, if a for-warding port fails or becomes disconnected, the STA will run again to recomputed the Spanning-Tree topology so that blocked links can be reactivated. By default, STP is enabled on all ports of a switch. STP should remain enabled in a network to prevent bridging loops from forming.

CCNA, CCENT, CCNP Tutorial on Routers and Routing

By M.Aslam

Routers are the critical part of all the networks and can be both security aid and security vulnerability. A router basi-cally has more network interfaces through which network traffic is forwarded. Or it might be blocked. The router decides when to forward packets between the networks based on internal routing table. The routing table can also be static. That means where each route is explicitly defined or dynamic where the router learns new routes by the use the routing protocols.

A router also supports access control lists that specify which packets to allow or blocked. Every packet going through a router will be checked against the ACL to see if the packet is allowed to be forwarded. Lots of current routers offer secu-rity capabilities along with their routing functionality. Seg-menting the network using routers limits the amount of the data flowing through segments. It also applies to broadcast traffic.

Routers also allow technicians to explicitly deny a few pack-ets the ability to be forwarded between segments. Using just the internal security features of some, routers can prevent users through internal network from using the Telnet to

Page 20: cisco

access external systems. Telnet are always a security risk as the passwords and all communications are transmitted in cleartext. Because of this, it's best not to create Telnet ses-sions between the internal network and an external network. Without a firewall, the rule can be put in place within the router to drop packets attempting to connect to port 23 on any external systems. After all of this is done by properly con- figuring the ACLs for the router. Spoofed packets are packets that contain the IP address in the header that are not the actual IP address of the originating the computer. Routers combat this by giving the technicians the ability to drop packets which are coming through the interface from the wrong subnet. . If the packet comes in from the router's external interface by using an IP address from the network on the router's internal interface, the router can be instructed to drop the packet and not forward it. There are two types of access lists available to filter traffic on Cisco routers. One of them is a standard access list. It allows technicians to filter traffic from specific addresses or subnet ranges. Cisco also provides extended access lists, which allow technicians to filter based on a variety of criteria. This access list allows technicians to use source addresses, destination addresses, and specific network services as the basis of filtering rules.

Free CCNA tutorial about Cisco IOS Software, Cisco Router Configuration modes and Cisco CLI (Command Line Interface).

By M.Aslam

The majority of Cisco routers run Cisco IOS Software with the command-line interface (CLI). The CLI is used to inter-face with the device and send commands to the device. This is achieved through the use of a terminal, a terminal emula-tor, or a Telnet connection. Some routing cards, such as the Multilayer Switch Feature Card (MSFC) daughter card for the Catalyst 6000 series LAN switches, also run Cisco IOS Software. Understanding the Cisco IOS Software CLI is as fundamental to supporting routers. There are three ways in which you can access the CLI: you access the router through the console; through a dialup device through a modem attached to the auxiliary port; or by using a Telnet connec-tion.

Whichever method you use, you enter user exec mode first. User exec mode is one of three command exec modes in the IOS user interface. Enable mode, also known as privileged mode or Privileged exec mode, and command mode are the others. Enable mode is so named because the enable com-mand is used to reach this mode.

Page 22: cisco

22

User mode allows commands that are not disruptive to be issued, with some information being displayed to the user. Privileged mode supports a superset of commands compared to user mode. However, none of the commands in user mode or privileged mode changes the configuration of the router. Passwords are required for Telnet and auxiliary access as of Cisco IOS Release 12.x and later. However, there are no preconfigured passwords; therefore, you must configure passwords for Telnet and auxiliary access from the console first.

All Cisco routers have a console port, and most have an auxiliary port. The console port is intended for local adminis-trative access from an ASCII terminal or a computer using a terminal emulator. The auxiliary port is intended for asyn-chronous dial access from an ASCII terminal or terminal emulator; the auxiliary port is often used for dial backup.
