Hello everyone,

Please see the attached ppt.  The question is:  is it possible to have both PCs on the same LAN accross the network with Foundry and Cisco switches?

Thanks,

Re: LAN between Foundry and Cisco

I would personally enable MPLS on both routers to link the lans..

You could probably also create a tunnel?

Maybe this will help?

Hell,

You could probably create a basic VPN between the two routers if you wanted.

LAN between Foundry and Cisco

If properly setup, there is no reason that would not work.

Jimmy, based purely on what you have in the diagram, this will not work because you can't have the same IP network existing in two locations and still be able to talk between the two.

There are a couple of options including those already mentioned. You may want to consider using bridging across the routers and connecting the two IP networks via layer 2 rather than having the two segments seperated by a layer 3 network between the two routers.

Another solution, and maybe the most feasible if the configuration as shown is set in stone, is to use NAT. It would require setting up static entries and no two IP addresses can overlap between the two segments, but it would work. A word of caution, this will likely result in a high degree of administrative headache after a while.
