The reason is as follows:
  • In the QinQ scenario, the distribution device adds a two-layer tag to a packet. Compared with the default MTU 1518 on the Ethernet, a four-byte tag is added. To facilitate operation and ensure redundancy, the MTU is uniformly changed to 1530.

Which devices and interfaces need to modify the MTU?
  • The MTUs of the core interfaces of the upstream aggregation devices and core aggregation interfaces should be set to 1530.
