NO.33 Which of the following statements disobey the basic principle of area division?

If the ISP runs OSPF protocol in the whole province network, then one city can be taken as one area.

In the network, there are some sub networks such as 110.1.1.0/24,110.1.2.0/24,110.1.3.0/24, 120.1.1.0/24,120.1.2.0/24 ,120.1.3.0/24.Then all the routers belonging to 110 network can be configured in one area.

One network maybe includes high-end, mid-end and low-end routers. Generally, all of these routers will be in same area.

Make all routers with larger routing-table into one area.

LAN switch can still operate normally even when loop exists.

LAN switch can detect loop according to the contents of the packet.

LAN switch can modify the data field of the forwarded frame when necessary.

To maintain separate VRF lor different VPN.

To allocate unique RT for each VPN.

To allocate different LSP for each VPN.

To allocate unique RD for each VPN.

LAN switch will modify the data link layer header of the packet and then forward it.

LAN switch can learn Mac address automatically.

LAN switch operates at data link layer.

LAN switch will modify the network layer header of the packet and then forward it.
