Description

Configure the device to allow LACP, LLDP, OAM LFM, and OAM CFM packets to cross the Layer 2 circuit. If the l2circuit-control-passthrough statement is not configured, LACP, LLDP, OAM LFM, and OAM CFM packets are classified as control packets and are not transmitted across the Layer 2 circuit.

Note:

For MX Series routers, the functionality that the l2circuit-control-passthrough command provides is performed automatically.

Starting in Junos OS Evolved Release 22.4R1, you do not need to configure the l2circuit-control-passthrough statement to allow tunneling of Layer 2 control frames between local and remote provider edge (PE) devices in a Layer 2 VPN on PTX10001-36MR, PTX10004, PTX10008, and PTX10016 routers.

This statement is not applicable for ACX routers running Junos OS Evolved.

Default

By default, this statement is not configured.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information
