    Table 1: show l2-learning instance Output Fields

    Field Name

    Field Description

    PBN Routing Instance

    Name of PBN routing instance.

    bridging domain

    Name of bridging domain.

    Index

    Number associated with the routing instance or bridging domain.

    Logical System

    Name of the logical system or Default if no logical system is configured.

    Routing instance flags

    Status of Layer 2 learning properties for each routing instance:

    • P2P—Point-to-point service (E-LINE).
    • MP—Multi-point service (E-LAN).
    • M1—Many service VLANS (S-VLANs) to one I-SID.
    • O1—One S-VLAN to one I-SID. This field is not yet supported and reserved for a future release.

    MAC limit

    Maximum number of MAC addresses that can be learned from each interface in the routing instance or bridging domain.
