Routerlabs
|
Welcome to Routerlabs. I started this website during my CCIE studies to help others with basic configuration of Cisco routers. Nobody want's to start each lab session by configuring IP addresses on interfaces, right? I passed my exam in October 2009 and became CCIE #25603. From time to time I add some more configuration for routers. The labs use dynamips or GNS3 as a simulator. You find the .net file with the router layout and the configurations for each lab. Please do not ask for IOS images. If you do not have an image buy one from Cisco.

IPv4 ends soon
Today two more /8 networks have been assigned to a RIR. The networks 50/8 and 107/8 have been given to ARIN. There are just 22 network blocks left. It is time to implement IPv6 in all networks.

CCIE #25603
I passed my lab on October 1st in Brussels. Most of my study material I post here on this website for all other candidates to learn from. I used this little labs for learning the technologies in isolated scenarios.

Training Lab online
The new lab with 4 routers and 3 Switches in online. You ca use the lab for testing and learning
Ethernet, Frame-Relay and Serial lines.

Ethernet Lab with Cisco Switch
The first lab of a new set is online. The ethernet labs have a Cisco Switch for
connecting the routers. This labs can be used for VLAN routing, etc.

What to use dynamips for
Dynamips simulates Cisco hardware on PCs. There are versions for Windows, Linux and MacOS. You need
an IOS image from Cisco. The image will be started in the simulator and you get the feeling of using
a real Cisco router. Ethernet, Frame Relay and ATM lines can be simulated. Do not expect the real
bandwidth or perfomance from this lines. Dynamips helps you to do the logical testing of your
network, it is not about performance.
Many candidates for CCNA, CCNP or CCIE use Dynamips to prepare for the exam.

New Lab
New lab online: 3 Triangle + One
|
11. October 2007
We go online!
Preconfigured Dynamips labs and Cisco documentation you will find here on this site. To test technologie, routing protocols, redistributing or features like MPLS or Multicast sometime litte preconfigured testlabs are needed. Here you find them. For a start the labs routers connected via serial lines and ethernet, frame relay will follow. Labs with mixed technologies will come soon.
