Description

Set a shared source Provider Backbone Bridging (PBB) MAC (B-MAC) address for all service identifiers (ISIDs) under a specified routing instance. If a source B-MAC address is derived automatically from the aggregated Ethernet system ID, you must specify the auto keyword.

For PBB-Ethernet VPN (EVPN) functionality, one service group (a group of ISIDs) can correspond to a single-homed, single-Active, or Active-Active scenario. You cannot mix and match service groups. For a shared B-MAC model, you configure one source B-MAC per service group using the routing-instances routing-instance-name pbb-options service-groups service-group-name hierarchy.

To specify a source B-MAC per ISID, use the routing-instances routing-instance-name pbb-options service-groups service-group-name isid isid-name hierarchy. If you do not specify the source B-MAC per ISID, then the B-MAC inherits from the B-MAC configuration located under the pbb-options setting.

The support of the source-bmac statement at the [edit interfaces interface-name unit unit esi] hierarchy level allows configuring of the Ethernet Segment Identifier (ESI) and source B-MAC address per logical interface, in addition to the existing support for physical devices.

Options

Length

Length of the B-MAC address.

  • Default: 48B

Required Privilege Level

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

Release Information

Statement introduced in Junos OS Release 16.1.

Support at the [edit interfaces interface-name unit unit esi] hierarchy level introduced in Junos OS Release 18.1R1.
