CCNA EIGRP LAB Question

Question:

After adding R3 router, no routing updates are being exchanged between R3 and the new location. All other inter connectivity and Internet access for the existing locations of the company are working properly.
The task is to identify the fault(s) and correct the router configuration to provide full connectivity between the routers.

Access to the router CLI can be gained by clicking on the appropriate host. All passwords on all routers are cisco.

IP addresses are listed in the chart below.

ccna_eigrp_sim

R1

Fa0/0: 192.168.77.33
S1/0: 198.0.18.6
S0/1: 192.160.60.25

R2

Fa0/0: 192.168.60.97
Fa0/1: 192.168.60.113
S0/0: 192.168.36.14

R3

Fa0/0: 192.168.77.34
Fa0/1: 192.168.60.65
Fa1/0: 192.168.60.81

R4

Fa0/0: 192.168.60.129
Fa0/1: 192.168.60.145
S0/1: 192.168.60.26

Answer and explanation:



We should check the configuration of the new added router first because it does not function properly while others work well. From the command line interface of R3 router, enter the show running-config command

ccna_eigrp_sim_show_run

From the output above, we know that this router was wrongly configured with an autonomous number (AS) of 22. When the AS numbers among routers are mismatched, no adjacency is formed.
(You should check the AS numbers on other routers for sure)

To solve this problem, we simply re-configure router R3 with the following commands:

R3>enable (you have to enter cisco as its password here)
R3#configure terminal
R3(config)#no router eigrp 22
R3(config)#router eigrp 212
R3(config-router)#network 192.168.60.0
R3(config-router)#network 192.168.77.0
R3(config-router)#no auto-summary
R3(config-router)#end
R3#copy running-config startup-config

Check R1 router with the show running-config command:

ccna_eigrp_sim_show_run_2

Notice that it is missing a definition to the network R3. Therefore we have to add it so that it can recognize R3 router

R1>enable (you have to enter cisco as its password here)
R1#configure terminal
R1(config)#router eigrp 212
R1(config-router)#network 192.168.77.0
R1(config-router)#end
R1#copy running-config startup-config

Now the whole network will work well. You should check again with ping command from router R3 to other routers!

Cisco IOS access lists: 10 things you should know

Takeaway: Access control lists (ACLs) are a fundamental part of working with routers. How much do you know about managing these vital gatekeepers? David Davis lists 10 things every administrator should know about working with Cisco IOS ACLs.

If you work with Cisco routers, you're more than likely familiar with Cisco IOS access control lists (ACLs). But that doesn't mean you know all there is to know about these important gatekeepers. Access lists are an integral part of working with routers, and they're vital to security.

Because ACLs are a fundamental part of router administration, I want to address 10 things you should know about working with these lists. If you're new to working with Cisco routers, this list offers a good foundation to get you started. But even if you've worked with Cisco routers for a while, it never hurts to review the basics—you might even learn something new.

So, without any further ado, here are 10 things you need to know about Cisco IOS access lists, beginning with the basic definition of an ACL.

What is an access control list?
In the Cisco IOS, an access control list is a record that identifies and manages traffic. After identifying that traffic, an administrator can specify various events that can happen to that traffic.

What's the most common type of ACL?
IP ACLs are the most popular type of access lists because IP is the most common type of traffic. There are two types of IP ACLs: standard and extended. Standard IP ACLs can only control traffic based on the SOURCE IP address. Extended IP ACLs are far more powerful; they can identify traffic based on source IP, source port, destination IP, and destination port.

What are the most common numbers for IP ACLs?
The most common numbers used for IP ACLs are 1 to 99 for standard lists and 100 to 199 for extended lists. However, many other ranges are also possible.

Standard IP ACLs: 1 to 99 and 1300 to 1999
Extended IP ACLs: 100 to 199 and 2000 to 2699
How can you filter traffic using ACLs?
You can use ACLs to filter traffic according to the "three P's"—per protocol, per interface, and per direction. You can only have one ACL per protocol (e.g., IP or IPX), one ACL per interface (e.g., FastEthernet0/0), and one ACL per direction (i.e., IN or OUT).

How can an ACL help protect
my network from viruses?
You can use an ACL as a packet sniffer to list packets that meet a certain requirement. For example, if there's a virus on your network that's sending out traffic over IRC port 194, you could create an extended ACL (such as number 101) to identify that traffic. You could then use the debug ip packet 101 detail command on your Internet-facing router to list all of the source IP addresses that are sending packets on port 194.

What's the order of operations in an ACL?
Routers process ACLs from top to bottom. When the router evaluates traffic against the list, it starts at the beginning of the list and moves down, either permitting or denying traffic as it goes. When it has worked its way through the list, the processing stops.

That means whichever rule comes first takes precedence. If the first part of the ACL denies traffic, but a lower part of the ACL allows it, the router will still deny the traffic. Let's look at an example:

Access-list 1 permit any
Access-list 1 deny host 10.1.1.1
Access-list 1 deny anyWhat does this ACL permit? The first line permits anything. Therefore, all traffic meets this requirement, so the router will permit all traffic, and processing will then stop.

What about traffic you don't specifically address in an ACL?
At the end of an ACL is an implicit deny statement. Whether you see the statement or not, the router denies all traffic that doesn't meet a condition in the ACL. Here's an example:

Access-list 1 deny host 10.1.1.1
Access-list 1 deny 192.168.1.0 0.0.0.255What traffic does this ACL permit? None: The router denies all traffic because of the implicit deny statement. In other words, the ACL really looks like this:

Access-list 1 deny host 10.1.1.1
Access-list 1 deny 192.168.1.0 0.0.0.255
Access-list 1 deny ANYCan I name an ACL?
Numbers—who needs numbers? You can also name your ACLs so you can more easily identify their purpose. You can name both standard and extended ACLs. Here's an example of using a named ACL:

router(config)# ip access-list ?
extended Extended Access List
log-update Control access list log updates
logging Control access list logging
resequence Resequence Access List
standard Standard Access List
router(config)# ip access-list extended test
router(config-ext-nacl)#
router(config-ext-nacl)# 10 deny ip any host 192.168.1.1
router(config-ext-nacl)# exit
router(config)# exit
router# show ip access-list
Extended IP access list test 10 deny ip any host 192.168.1.1What's a numbering sequence?
In the "old days," you couldn't edit an ACL—you could only copy it to a text editor (such as Notepad), remove it, edit it in notepad, and then re-create it. In fact, this is still a good way to edit some Cisco configurations.

However, this approach can also create a security risk. During the time you've removed the ACL to modify it, the router isn't controlling traffic as needed. But it's possible to edit a numbered ACL with commands. Here's an example:





router(config)# access-list 75 permit host 10.1.1.1
router(config)#^Z
router# conf t
Enter configuration commands, one per line. End with CNTL/Z.

router(config)# ip access-list standard 75

router(config-std-nacl)# 20 permit any
router(config-std-nacl)# no 10 permit 10.1.1.1
router(config-std-nacl)#^Z

router# show ip access-lists 75
Standard IP access list 75 20 permit any
router#How else can I use an ACL?
ACLs aren't just for filtering traffic. You can also use them for a variety of operations. Let's look at some of their possible other uses:

To control debug output: You can use the debug list X command to control debug output. By using this command before another debug command, the command only applies to what you've defined in the list.
To control route access: You can use a routing distribute-list ACL to only permit or deny certain routes either into or out of your routing protocol.
As a BGP AS-path ACL: You can use regular expressions to permit or deny BGP routes.
For router management: You can use an ACL to control which workstation or network manages your router with an ACL and an access-class statement to your VTY lines.
For encryption: You can use ACLs to determine how to encrypt traffic. When encrypting traffic between two routers or a router and a firewall, you must tell the router what traffic to encrypt, what traffic to send unencrypted, and what traffic to drop.
To wrap up this review, I'll leave you with one last tip: Don't forget to use remark statements in your ACLs. They'll come in handy when you have to troubleshoot something later.
