I've configured my Cisco home lab with a router that connects to cable internet and a switch with VLANs.
Now it's time to add a new device to the Cisco home lab, a Cisco Aironet 1240AG wireless access point for wireless connection.

And by the way, the image on the left is not an official logo from Cisco or anything, I just made that up.

I won't configure anything fancy this time, only give basic administration configuration and set up an open SSIDs also associate the SSIDs to VLANs.

Since I want to configure two SSIDs - one is free for all SSID with no authentication and the other one with authentication - for the wireless network, I need to configure additional VLAN on the switch.

I have already the VLAN 30 for the wireless network and want to add VLAN 40, so in total there would be 5 VLANs in my Cisco home network lab.

I made a network diagram with Cisco Aironet 1240AG wireless access point added in the picture below:

So lets start the configuration on the next post, there are some steps to complete this Cisco home lab network diagram if you haven't done so.

Starting from the wireless access point I'm going to configure the basic administration configuration such as the access point's management IP address, SSIDs and associate them to VLANs, optionally configure the authentication security options for the SSIDs, and establish trunk connection to the switch.

For the switch I'll configure VLANs and the trunk connection to the access point and the router.

Last in the router I'll configure interVLAN routing, DHCP server for each VLAN, and other configurations like I've posted before.

If you are a typical American, you will need to learn to appreciate how real maple syrup is made.  I had a facinating time while reading this DIY on how to make maple syrup/wine from real maple trees.

It’s as simple as draining the maple water from the maple tree then boiling it until you get your nice maple syrup.  Yes, this can be great food-enhancer whenever you are eating pancakes, French toasts, etc…etc…

If you have even 1 maple tree in your backyard, we highly suggest you to make at least one cup of maple syrup and try it on your breakfast.

We use a commercial “Sap Sack” to collect the sap after trying many on hand methods that are more pain than fun. These work very well and hold about 3 gallons of sap.

The sap starts to run as soon as above freezing days occur and stops if it stays above freezing for more than a day. It also stops at night when it freezes but then resumes in the morning if it warms up again.

The sap is simply water containing about 3% sugar that was produced by the leaves in Fall and stored in the roots. In Spring this sugar is required by the new buds for development. When the new leaves start photosynthesizing and producing sugar, the flow stops completely.

Google's been the lone hold out among major search engines on RSS but the company quietly enabled feeds for web search results this week. The offering is pretty limited and frustrating, you have to go through Google Alerts to get an obscure RSS URL, but we offer a tutorial and some strategic advice in this post.

Web search RSS is useful for being alerted whenever search results for your keywords or link have changed; subscribing to at least a few searches will let you know when Google users are seeing something new in the first few pages of search results for your company name, for example.

How to Get the Feeds

All the other major search engines make it really easy to grab a feed for any web search, but Google is probably concerned about spammers finding bizarre and unscrupulous uses for its feeds. We're all inconvenienced as a result.

To get a feed for a Google search you have to go to the web page for Google Alerts and set up an alert for your search. You can enter most queries here, including site: queries. (site:http://readwriteweb.com semantic for example.) You should select "web" instead of the default "comprehensive" if you're just interested in tracking web search results.

"Feed" isn't an option in the initial drop down menu of delivery options, you've got to select email first. After you've done that, look at your collection of alerts and click to edit the one you want by RSS. At this point "feed" is an option in the drop down menu. Select it and you'll be shown an RSS URL. Throw that puppy in your favorite feed reader and you're ready to rock and roll.

The feed will deliver any new links that show up in the top 20 search results for your query. That's pretty limited, but most people don't look beyond the first 20 results anyway. That means that this is good for high-level reputation tracking but not very good for discovery of new, more obscure pages of interest.

The RSS URLs that Google gives you are based on an arbitrary number and don't contain the text characters of your query. That means you can't build more feeds by simply editing the URLs, you have to go back in through Alerts and repeat the proccess for every feed of interest.

Update: One day after we wrote this post, the official Google Blog just announced the availability of feed alerts as well.

More Advanced Options

Here's how we're using the new Google search feeds. We've grabbed feed URLs for searches for A. our names, B. our company name, C. our company URL and (just for fun) one for each of those three items without the other two. For example: "Richard MacManus" -readwriteweb -http://readwriteweb.com.

That gave us a small pile of feeds, which we then ran through our favorite RSS splicing and deduplication service (we used Yahoo Pipes but if you're not comfortable with Pipes then Feed.informer.com is really easy to use). We spliced all these feeds together, filtered for duplicates and then threw the resulting feed into our highest priority feed reading system.

Now we can track our high level reputations constantly, without being paranoid about it. We might do this for concept searches as well so that if someone new starts ranking really high for topics we specialize in (semantic web, RSS) then we'll know about them and never look ignorant at parties.

If we were interested in getting an RSS feed for Google web search for discovery, more than just reputation tracking, we might do an "advanced search," increase the results displayed from 10 to 100 and then use Dapper.net to scrape a feed of results from that page.

All of this is more complicated than it ought to be, but once you set up even the most basic feed options then you don't have to think about it again. Though it isn't perfect, we do appreciate Google making these feeds available.

Configure Router for InterVLAN routing

If you only configure VLAN on the 2950 or other layer 2 switches, the clients can only communicate with other clients within the same VLAN.
If you want them to be able to communicate with other clients on different VLANs, then you need to configure a router for interVLAN routing.

Configuration of router for interVLAN routing often called router on a stick. The reason is the clients that want to communicate with other clients on different VLANs need to go through the router first and the router will route the packets to the appropriate VLANs back through the same line.

The disadvantage of this is that single line going to the router will be filled by requests from one VLAN going to other VLAN, and the router will be set for handling the routing for this.

No problem for the small LAN, but if you have a huge number of clients, you need to consider using Layer 3 or multilayer switches (Cisco Catalyst 3550 series or above) for interVLAN routing.

The concept of layer 3 switch routing is something that you'd find on the CCNP level, not the CCNA.
I don't have layer 3 switch, the cheapest one I can find in my local area is more than $600 yikes. But the configuration is so easy, I'll only want to give you some snippets later.

For now lets configure the router to do interVLAN routing.

We know that routers have limited amount of physical interfaces right? The 2611 have a default of 2 ethernet interfaces.
One interface is going to the internet and the other is supposedly connected to the internal LAN.
How come one interface can handle multiple VLANs a.k.a. multiple networks with different subnets.

There's a genius way to get around this, that is by using logical sub interfaces. That one port can be logically devided into many sub interfaces.
Each sub interface will handle one VLAN/subnet.

NOTE:

Previously the interVLAN routing can only be done by routers with Fast Ethernet interfaces (100 Mbps) and not intended for Ethernet interfaces (10 Mbps) due to small bandwidth consideration. But now we can configure it on the ethernet ports also.

Before configuring the router, lets see again how the network diagram looks like:

So we need to define four sub interfaces and the respective IP addresses, we also need to define the VLAN assigned to the sub interface using encapsulation dot1q VLAN_NUMBER, where the VLAN_NUMBER is the VLAN ID for the sub interface.
You need to define the VLAN first on the sub interface, then you can assign IP address there.
You don't need to assign IP address for the main interface ethernet 0/0 but do no shutdown and the sub interfaces will automatically apply the same no shutdown.
here's how we configure them:

router> enable
router# configure terminal
router (config)# interface ethernet0/0
router (config-if)# no ip address
router (config-if)# no shutdown
router (config-if)# interface ethernet0/0.5
router (config-subif)# encapsulation dot1q 5
router (config-subif)# ip address 192.168.5.1 255.255.255.0
router (config-subif)# interface ethernet0/1.10
router (config-subif)# encapsulation dot1q 10
router (config-subif)# ip address 192.168.10.1 255.255.255.0
router (config-subif)# interface ethernet0/1.20
router (config-subif)# encapsulation dot1q 20
router (config-subif)# ip address 192.168.20.1 255.255.255.0
router (config-subif)# interface ethernet0/1.30
router (config-subif)# encapsulation dot1q 30
router (config-subif)# ip address 192.168.30.1 255.255.255.0

You can give sub interface number up to 4294967295, the reason is it gives you the flexibility on naming the sub interface to match the VLAN ID. You can easily identify the sub interface e0/1.5 is for VLAN 5 and so on.

Oh, don't forget to do the no shutdown command on the main interface ethernet 0/1, it will also do no shutdown for the sub interfaces.

Now if you can successfully ping the interface VLAN 5 on the switch (192.168.5.2 in this example) then you are done configuring the router for interVLAN routing.

For configuring interVLAN routing on Layer 3 switches you have to make interface VLAN for every VLAN that you want to route and give them IP addresses.

Layer3Switch> enable
Layer3Switch# configure terminal
Layer3Switch (config)# interface VLAN 5
Layer3Switch (config-if)# ip address 192.168.5.1 255.255.255.0
Layer3Switch (config-if)# no shutdown

Do this for every VLAN that you want to route, you don't need to configure sub interfaces on the router.
The layer 3 switch will do the routing for the VLANs without ever need to send anything to the router first.
But you need to activate the ip routing feature on the switch first, if it's not already activated using:

Layer3Switch (config)# ip routing

Very simple right?

Last things left is to configure the router for additional configuration, DHCP server for each subnet, connect to the cable internet, and other details on the next post.

So I was sitting and thinking about what to post next in my blog, and hey why not continuing on the last posts about setting up Cisco home lab.

The network topology might not be the best topology for CCNA home lab, but the configuration should be similar with any other topologies.

Let's take a look at the last network topology where I connected 2611 router to the cable internet:
I'm going to add a Cisco switch, 2950 Cisco switch that is. And I'll be adding some VLANs to it, I'll separate the PCs in my LAN into four different networks.

• VLAN 5 as the native VLAN - 192.168.5.0 network
• VLAN 10 for the office - 192.168.10.0 network
• VLAN 20 for the home - 192.168.20.0 network
• VLAN 30 for wireless - 192.168.30 network

In network diagram view, you can see it like this:
This is just a very simple network diagram, but most SOHO networks are typically look like this, maybe with some additional switches here and there.

You can see above the details of the network with exception of the wireless network, I'll leave the wireless network configuration for later posts but still provide a VLAN for wireless connectivity.

Same with the previous posts, I'll do the configuration on series and hopefully in the end I can make a full Cisco home lab scenario for Cisco certification exam.
