How to make inter routers communicate with each other over the same VLAN devices, and different VLAN does not communicate
LZ, you can't do this wiring.On the same router, different Ethernet interfaces are not allowed to distribute duplicate segments. So your claim is wrong in itself.Your router can be changed into a three layer switch. Then do not open the three layer function, you can meet the requirements of this topic, or need to connect the outer net, then do ACL.
MPLS, it depends on whether your application is so complicated. Is that necessary?. In this case, both the PE and P devices are on the router. It's no trouble at all. On the whole, the problem was completely solved on the two floor.
The router two port uses the VLAN three layer interconnection or sub interface to terminate the VLAN, then the switch between the two switches to the router is the three layer environment, and it has nothing to do with the VLAN. This time you need fine QOS or advanced ACL to control access between address segments or IP addresses.
The router interface uses the Ethernet port and works in the two - layer mode, or is it direct TRUNK?. Equal to when the switch is used.
