making a topology with cisco and juniper routers
We have 8 routers in total.
6 cisco routers and 2 juniper routers....can anyone suggest a simple possible topology with these given routers to implement BGP, OSPF and MPLS at a time... it would be really helpful for me if you can attach the diagram along with your answer telling me all the OSPF areas, AS and other related parameters?

What are the interfaces per router and which interfaces do you have the crossover cables to connect them together.
ASKER
Thanks a lot for your reply
There are 4 interfaces per router....2 eth and 2 serial
I just need a simple topology so that BGP, OSPF and MPLS can be configured easily in it

Any switches? or are your ethernet just crossover?
ASKER
I have 1 switch with 16 fast ethernet ports
Ok you most likey want an MPLS network running BGP over sort of a WAN link and the OSPF as you IGP is this correct? What I would sugest (if you have a router that can take the interfaces) is to build out one of your routers as a MPLS core router with at least 4 serial interfaces. I am not an expert on MPLS so what I say about the MPLS portion is going to be best guesses from my experience with it. I believe you can setup the MPLS network over the frame switch with some VRF statements on the FR switch. again not sure about that. This would then connect 4 routers to simulate four sites with two additional routers to either hang off two sites or a main site. With these two additional routers you can have them dual connected so that you could test to make sure that you can manipulate your OSPF network to except the routes you want them to have or they could be connected seperate and not dual homed to the network . Also how many OSPF areas are you looking for and what types are you looking to emulate.
Let me know if this is what your looking for and what your site preferences are.

You said: "Ok you most likey want an MPLS network running BGP over sort of a WAN link and the OSPF as you IGP is this correct?"
Yes, this is exactly what I want and I didnt really get much what you said afterwards since I am not an MPLS expert either
I am looking for like 2 or 3 areas in OSPF and 2 AS in BGP

suppose if I want to swap the AS into OSPF areas and OSPF areas into the AS in your diagram....will that be technically correct? like I want 3 OSPF areas in 1 AS, with 3 other AS connected to it
ASKER
correction: I meant 4 OSPF areas in 1 AS and 3 other AS connected to it
You wouldn't need to run BGP on all your routers just the edge. Is this what you want or are you wanting bgp on all routers?
ASKER
Actually I was willing to run OSPF inside an AS.....opposite of you have designed....can you redo your design making OSPF areas inside an AS connected with another AS

Thanks for your reply
So we can also easliy implement MPLS in it too, right?
Can you shed some light on that please?
