Configuring general Layer 2 forwarding
NOTE:
General Layer 2 forwarding is available only at the command line interface (CLI).
Working mechanism
If the destination MAC address of an incoming packet matches the MAC address of the receiving Layer
3 interface, the device forwards the packet through that interface. If not, the device performs general
Layer 2 forwarding through a Layer 2 interface. The device looks up the MAC address table according
to the destination MAC address of the incoming packet, obtains the outgoing interface, and then
forwards the packet through the interface.
Configuration procedure
General Layer 2 forwarding is enabled by default.
