Subscriber Management and Services

  • L2TP session lockout support (MX Series)—Starting in Junos OS Release 21.1R1, you can specify the lockout-result-code and lockout-error-code options to control the L2TP access concentrator (LAC) behavior in the Layer 2 Tunneling Protocol (L2TP) session lockout state.

    [See lockout-timeout (L2TP Destination Lockout).]

  • Support for PWHT (over EVPN-VPWS, on a transport logical interface) with subscriber management (BNG) service logical interfaces (MX Series routers)—Starting in Junos OS Release 21.1R1, you can deploy broadband network gateways (BNGs) that are connected to aggregation networks running EVPN-VPWS. You configure pseudowire headend termination (PWHT) on a transport logical interface that is on the pseudowire subscriber interface. The BNG pops the EVPN and VPWS headers and terminates subscribers at Layer 2.

    This feature includes support for:

    • All broadband features available on PWHT on MX Series routers
    • Single-homed EVPN-VPWS with the pseudowire subscriber interface anchored to a logical tunnel (LT) interface
    • Choice of whether or not to use a control word
