OSPF with InterVlan Routing

[Muhammad1Ali]

Dear All,

Please help me about it ...

The same network I have designed and working fine on the RIPV2 but I want it on the OSPF but it works on the packet tracer but not on the GNS3. In this diagram there are multiple areas and there are three ABRs connected to the backbone area. The others interfaces are in the area1, area2 and area3 respectfully and in that side I need the intervlan routing.

Is it possible in the ospf the same like in the diagram ?

What type of OSPF (Point to Point or Point to Multipoint ) will be required as the R1 is the backbone router further connected with the Internet on the BGP. ?

Please sir, advise me about it.

Thanks

Best Regards

It's perfectly possible to do what you want with OPSF.

What are the links between the ABRs and R1 configured as ?

What are your OPSF neighborships showing as ?

Where are you missing routes ?

Hi Jon,

Thank you very much,

1) The link between the ABRs and R1 is the wireless 1.4gig bridge link on the 5Km distand and the interface is configured with IP ospf network point-to-point.

2) On the packet tracer all the neibour displayed with its router-id, even on GNS3 but it does not show the route of other interface like area 1 or area 2.. Means the backbone router do not show the routes of other areas..(area 1 or area 2 and area 3)

3) i have tried alot and i dont think that i missed any route but the backbone area do not show the routes of subnterface (for Vlan, Router on the Stack).

Thanks

Ali
