IxNetwork : Using IxNetwork NextGEN Framework Configuring OSPF- Blog3

In my previous blogs I have configured basic IP connectivity between IxNetwork and DUT. Now In this blog we will be configuring routing protocols between Ixia and DUT which is ASR903 router in my case. If you have not seen my previous blogs already you can check that here Blog1 Blog2 .

Lets get started with the configuration.Following is the network topology, this is the same topology I have used in my previous blogs.

Once you have configured IP address connectivity between Ixia and DUT then it becomes very easy to configure routing protocols. Following are the steps you can use to do it.

Step 1 :  Follow my previous blog to add ports and enable IP connectivity between Ixia and DUT. Although I have two ports going to Ixia but to keep the blog simple I will configure OSPF just on one port. The same step can be followed to enable it on another port.

Once we are done with basic IP connectivity we will have our scenario like this :

Step 2:  You need to hover your cursor on IPv4 1 Option and you will see five option appear.

Here 1st two options are to enable or disable protocols the 3rd options with the (+) sign is the one which we need to use to add protocol. Click on third options and you will get options to add ospf protocols to the topology.

Step 3: We get following screen when we click on Add protocols (3rd option). In this screen you can select the protocol that you want to add, OSPFv2 in this case. Once selected click OK to move forward.

Step 4 : Once you click OK you will see OSPF stack added over IPv4 option. You can change OSPF options like area ID , neighbor ID etc by clicking on OSPF stack.

You can scroll the OSPF protocol options rightwards to change it.

I have selected area ID as 0.0.0.0 and neighbor ID as 20.20.20.1 which is assigned on DUT ASR903 interface. And following is the configuration on ASR903 for OSPF.

ASR900#sh run | sec ospf
router ospf 1
network 20.20.20.1 0.0.0.0 area 0

Once all options are configured you need to right click on OSPFv2 Options and start the protocol.

This will start OSPF process on Ixia and will bring up the ospf connection between the router and Ixia. You will see following message.

In my next blog I will discuss about configuring more than one OSPF neighbors on single interface and also about injecting routes to DUT. Stay tuned Thank you.
