End VLAN on vro

I have seen several posts on VLAN termination on the vrovlan Forum over the past two days. I found that the concepts of VLAN and routing are still confused. I will use the figure below to clarify the concept. Www.2cto.com is a very common LAN. I believe everyone can understand it. The simplest port VLAN is used as an example, VLAN2 and VLAN3 on two three-layer switches form the communication between the left-side PC of VLAN2 and the right-side PC of the two virtual LAN VLAN2 in the LAN. VLAN tags are added to the packets, VLAN3 also communicates with PCs on both sides. Summary: lan 1 Virtual LAN 2.
But what if I add a vro in the middle?
The vro divides the LAN into LAN1 and LAN2. Therefore, VLAN1 in LAN1, VLAN2 and VLAN1 in LAN2 are not the same virtual LAN. When a packet is routed, the vlan tag is discarded. Summary: Lan 2 Virtual LAN 4.
Therefore, when you come up with the concept of "cross-vro same VLAN" or "cross-vrovlan different VLAN", think carefully about the concept of "VLAN ends at vro.
