Dynamips Lab: OSPF Point-to-Multipoint Configuration
Posted by Aragoen Celtdra on August 8th, 2008
So I was thinking, since I’ve been doing a lot of dynamips/dynagen labs for practicing routing, I thought I should start posting them as well so my blog friends can try them out and/or point out mistakes I might have made. I thought it might be a good way to collaborate with others and also maybe to help out others who don’t have home lab setups.
Since there are many websites out there doing tutorials, video instructions (read blindhog 
), and other general information that pertain to Dynamips/Dynagen, I thought I would just focus on specific exercises that cover what I’m currently studying. It makes sense anyway in that this whole website is dedicated to specific things that pertain to my study. And a lot of my regular readers are also folks who are in the same boat as I am.
Most of my examples will be based mostly on examples from Cisco Press’ BSCI Authorized Study Guide. A few of them like the one you see below will be based from some Cisco documents in the DocCD. If I find other interesting configuration examples on the Internet that I’d like to “lab out” I’ll be posting them up as well.
The first of (hopefully) many labs to come will be an OSPF point-to-multipoint configruation from Chapter 4 of the study guide. The actual example was modified from an example in Configuring OSPF document from the Cisco website.
Let’s start with the topology:
Here is the dynagen configuration (.net) file:
autostart = False
[localhost]#
[[7200]]
image = \Program Files\Dynamips\images\c7200-js-mz.123-45.bin
npe = npe-400
ram = 160#
[[ROUTER R1]]
s1/0 = F1 1
model = 7200#
[[ROUTER R2]]
s1/0 = F1 2
model = 7200#
[[ROUTER R3]]
s1/0 = F1 3
model = 7200#
[[ROUTER R4]]
s1/0 = F1 4
model = 7200#
[[FRSW F1]]
1:102 = 2:201
1:103 = 3:301
1:104 = 4:401
2:203 = 3:302
Tasks:
- Configure the serial interfaces with the corresponding IP addresses
- Configure the ip ospf network point-to-multipoint interface command
- Configure the encapsulation frame-relay on the interfaces
- Configure the frame-relay map commands on all the routers to map ip to DLCIs.
- Configure OSPF
My previous post has the partial configurations. Stay tuned for the rest of my configurations and show command output…

I like your tutor …
can u show that konfigurations .. ???
