Layer 2 Circuit
Juniper-Cloud Native Router supports Layer 2 circuits over an IP/MPLS-based service provider's network. This topic provides configuration and verification details.
Juniper Cloud-Native Router supports Layer 2 circuits for a point-to-point Layer 2 connection over an IP/MPLS-based service provider's network. To establish the Layer 2 circuit, it uses Label Distribution Protocol (LDP) as the signaling protocol to advertise the ingress label to the remote PE routers. A targeted LDP session is established between the loopback addresses of the two PEs to exchange VPN labels. For more information on L2 circuits, please review Layer 2 Circuit Overview.
The following Layer-2 circuit features are supported by the Cloud-Native Router:
-
Enable
l2circuitprotocol on Physical (PF/VF), VLAN sub-interface, bond interface (towards core), and pod interfaces - Ethernet CCC encapsulations—
ethernet-cccandvlan-ccc -
Local interface switching
-
Control word
-
Protect Interface for CE redundancy
- Backup Neighbor for Core redundancy
-
Pseudowire cold and hot-standby
-
Support L2 circuit with BGP-Labeled Unicast (BGP-LU)
-
Support for dual VLAN tagging
-
Interoperability with other Junos devices
Configuration
You can configure Layer 2 circuits in Juniper Cloud-Native Router using configlets. Multiple configlet samples are provided in this section based on the
following topology:
For Layer 2 circuit configuration, you configure the Ethernet-based CE-facing interface
with the CCC encapsulation type of your choice—ethernet-ccc or
vlan-ccc. The Layer 2 circuit configuration such as the remote PE
neighbour (usually the loopback address), the interface connected to the CE-router, and a
virtual circuit identifier for the virtual circuit (VC) is performed under the edit
protocols l2circuit statement. Eventually, you configure MPLS, LDP and an IGP to
enable signaling for your Layer 2 circuit. Please review Example: Enternet-based Layer 2 Circuit
Configuration for a end-to-end Junos configuration example.
- Layer 2 Circuit with ethernet-ccc
- Layer 2 Circuits with vlan-ccc
- Layer 2 Circuit with Local Switching
- Layer 2 Circuit with Ignore Mismatch
- Static Layer 2 Circuits
- Layer 2 Circuit with BGP-LU
- Configuring via JCNR-CNI (Pod Configuration)
Layer 2 Circuit with ethernet-ccc
Configure Ethernet CCC encapsulation on CE-facing Ethernet interfaces on PE-1 (JCNR) that must accept packets carrying standard Tag Protocol ID (TPID) values.

kubernetes.io/hostname: node-1Layer 2 Circuit with Local Switching
You can configure Layer 2 circuit with local switching. Optionally, configure
protect-interface for local or remote end to ensure traffic switch over
when the primary interface goes down. Protect interfaces act as backups for their
associated interfaces that link a virtual circuit to its destination. The primary
interface has priority over the protect interface and carries network traffic as long as
it is functional. If the primary interface fails, the protect interface is activated.
Optionally, configure no-revert to prevent switch back to primary when
primary interface is back up.
