Layer 2 Protocol Tunnel Interface
To configure the interface where Layer 2 protocol tunneling is enabled, you can include the interface ge-fpc/pic/port statement at the following hierarchy levels:
- [edit protocols layer2-control mac-rewrite]
- [edit routing-instances routing-instance-name protocols layer2-control mac-rewrite]
Keep the following guidelines in mind when configuring Layer 2 protocol tunneling:
- Layer 2 protocol tunneling is supported on MX Series routers with enhanced queueing Dense Port Concentrators (DPCs).
- Layer 2 protocol tunneling must be configured on the interfaces at each end of the tunnel.
- You can enable Layer 2 protocol tunneling for untagged interfaces and single-identifier tagged interfaces only.
- For single-identifier tagged ports, configure a logical interface with the native VLAN identifier. This configuration associates the untagged control packets with a logical interface.
- You cannot enable Layer 2 protocol tunneling for double identifier tagged interfaces.
