Cheers matey.

There is just chaff all on here in relation to Cisco, so I'm trying to restore the Cisco v Microsoft balance single handed

 

Cisco > MS

 

I'm getting deeper inside OSPF!

- Learning about Area Border Routers that perform the summarization between two areas.
- Autonomous System Routing Border which basically connects you to different networks most commonly the internet.
- Everything must connect back to Area0 which is the backbone
- All 'areas' must share the same routing topology otherwise the summarization goes a bit 'pete tong'.

Oh and I got my CCENT certificate today, very nice

 

Haha, you have to bring a bit of fun to the Cisco world, otherwise it can become a bit stale

 

I have just done some changes to the routing scheme of my Lab to create two areas for OSPF.

- Area 0 being the backbone has four networks
- Area 1 has seven networks


Router NLR01 is going to be the Area Border Router. The Lab now looks like this:



Will post configs when its all up and running.

 

Haha, not as lucky as you matey!

I could borrow 4 x PIX's from work, but to be honest I can do pretty much everything on the CCNA level by using Packet Tracer so there seems little point in having a wiring closet in my Study.

If I do decide to go onto the CCNP at some point, I will definatley invest in a nice rig.

 

Just finished studying and rejigged my network diagram slightly with NLR02 being the Area Border Router.

I will load up the details in the morning, but I have to tell you it's looking sexy

 

Below is the finished network with OSPF in place. As mentioned, I have changed NLR02 to be the Area Border Router. The only thing I couldn't use was the route range for autosumarization. But if you check out the running configs in my next post, you can see that I have used the sumarization in the wild card mask.

I also changed the Router ID to be 1.1.1.1 for NLR01, 2.2.2.2 for NLR02 etc.
