Configuring inline Layer 2 forwarding
Working mechanism
The inline Layer 2 forwarding feature falls into the following types:
• Forward type—A packet coming from one interface goes out of another. The packet is forwarded
through the specified incoming and outgoing interfaces, rather than through looking up the MAC
address table. A complete configuration contains an ID, which uniquely identifies an inline Layer 2
forwarding entry, and two interfaces.
• Reflect type—A packet is forwarded through the interface that received the packet. A complete
configuration contains an ID, which uniquely identifies an inline Layer 2 forwarding entry, and one
interface.
• Blackhole type—A packet received on an interface is discarded. A complete configuration contains
an ID, which uniquely identifies an inline Layer 2 forwarding entry, and one interface.
The inline Layer 2 forwarding feature is supported on interfaces and subinterfaces.
