Hi All, I am wondering if the VLAN number is valid locally on a LAN only or it goes across the WAN link? In my scenario, I have two LANs separated with 2 WAN routers. On the LAN # 1, I assign a VLAN 100 with IP address (gateway) of 10.100.1.1. On LAN # 2, I assign another VLAN 100 but with an IP address of 10.200.1.1. The WAN link is using a 172.16.10.0 subnet, and does routing between 10.0.0.0 and 172.16.10.0 networks.
My question is that will VLAN 100 on LAN # 1 distinguishes from VLAN 100 on the LAN # 2? Can I have 2 different subnets with the same VLAN ID number but sitting on 2 separate LANs? Hosts in the first VLAN 100 should not talk to others in the second VLAN 100 without using the routers? Thanks All!
