OSPF lab help.


I am trying to set up an OSPF lab for running 5 Modes of ospf Operation.I am confused how can i make a framerelay cloud to run this.Can some some help me to achive this.

Thanks in advice



Re: OSPF lab help.

When I was doing my NetAcad and trying to get ospf working over fr, I had to use the commad ip ospf network broadcast before my ospf routes were sent. I think. Eventually I got the FR working with OSPF though.

If you would post alittle bit more info, I'd be happy to look it over.

Re: OSPF lab help.

I am not sure if I understand the question

Are you trying to build a frame relay cloud?

If yes, then you need a router like a Cisco 2522 as your frame relay switch.

Then you connect all your serial cables from all the other routers to this

Switch/router to simulate frame relay

Hi Lijesh,

you need any low end cisco router with four or more serial interfaces to fit to your topology. You can have 2522 with 10 serial interfaces or can have any 2600 with NM-4AS or NM-8AS card. The rest is easy to configure it as frame relay switch. Here is the link which shows how to configure.
