Layer 2 Features

  • Support for IRB in VRF instance (PTX10001-36MR, PTX10003, PTX10004, PTX10008, and PTX10016 Packet Transport Routers)—Starting in Junos OS Evolved Release 22.4R1, we introduce support for integrated routing and bridging (IRB) in a virtual routing and forwarding (VRF) instance. This support enables forwarding of Layer 3 (L3) VPN traffic from the IRB interface towards the CE and forwarding of L3 VPN traffic towards the core.

    The IRB interface enables routing of L3 traffic between a bridge domain and another routed interface. To set up your IRB interface, use either enterprise-style configuration or service-provider-style configuration.

  • Support for MAC addresses at chassis level (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 22.4R1, you can configure a MAC address for the entire chassis. To configure a MAC address for the entire chassis, use the local-station-mac mac-address configuration statement at the [edit chassis] hierarchy level.
