I have a question about how to get a different subnet to cross routers.
Basically I have a device on the inside of the main router that uses 10.41.4.65 subnet 255.255.255.192. It is setup that only devices in its same subnet are allowed to talk to it. So on the PCs on the inside of the main router we simply gave them secondary IPs in the 10.41.4.64/26 subnet and put route statements on them to point to the 10.41.4.65 device for the network on the other side of it. No problem works like a champ.
The problem comes when we have 4 PCs at different locations (2 at one location 2 at another) that all have to come through there own routers that connect to the main router and need to have the same functionality as the PCs on the inside of the main router.
Clear as mud? Please any assistance is appreciated.
I am attaching a drawing of the current settings.
You need either:
1.) 802.1Q tunneling over a layer-2 cloud
2.) L2TPv3 over a layer-3 cloud
3.) MPLS VPN over a layer-3 cloud
Any of these will do the job for you. #1 is the least complex and probably the easiest to configure. Similarly, #3 is the most complex, and probably the hardest to configure, but is also the most capable.
