Subscriber Management and Services

  • BGP support over dynamic PPPoE subscriber interfaces (MX480 and MX960)—You can enable BGP over dynamic PPPoE interfaces for IPv6 family on routers with MPC2, MPC5, and MPC7 line cards. To enable this support, configure routing services with the routing-service statement in both the PPPoE subscriber dynamic profile and the dynamic profile for the underlying VLAN interface. You can also enable routing services for subscribers over pseudowire interfaces when a non-demux dynamic underlying VLAN is configured.

    [See Enabling BGP over Dynamic PPPoE Subscriber Interfaces.]

  • Operational continuity for pseudowire subscribers over RLT (MX304, MX960, and MX10004)—You can instantiate pseudowire subscriber logical interfaces over a redundant logical tunnel (RLT) interface in active-active or active-backup mode to maintain operational continuity. This configuration ensures uninterrupted service by activating new subscribers and keeping existing subscribers operational if an RLT member interface goes down due to a Packet Forwarding Engine disablement. Subscribers remain up as long as at least one RLT member link is on an active Packet Forwarding Engine.

    [See Anchor Redundancy Pseudowire Subscriber Logical Interfaces Overview.]

  • MAC address validation support for IPv6 interfaces (MX204)—You can enable MAC address validation feature on interfaces configured with IPv6 addresses. This feature allows the router to validate that incoming packets contain both a trusted IP source and a MAC source address. You can configure the following two modes to take action based on validation:

    • Strict: Drops packets that fail validation.

    • Loose: Forwards packets even if validation fails.

    You can enable MAC address validation on both static and dynamic interfaces. For static interfaces, use the set interfaces interface-name unit logical-unit-number family inet6 mac-validate (loose | strict) command. For dynamic interfaces, use the set dynamic-profiles profile-name interfaces demux0 unit logical-unit-number family inet6 mac-validate (loose | strict) command.

  • Support for IPv6 subscribers over Soft-GRE tunnels (MX240, MX480, and MX960)—Wi-Fi Access Gateway (WAG) supports IPv6 Soft Generic Routing Encapsulation (Soft-GRE) tunnel creation for carrying IPv4 and IPv6 traffic. The following IPv4 Soft-GRE tunnel features also support IPv6 Soft-GRE tunnels:

    • Static subscriber support over statically configured Soft-GRE tunnels

    • PPPoE support over Soft-GRE tunnels with active/active and active/backup RLT modes

    • Retrieve soft-GRE information through Junos telemetry

    You can use the existing Soft-GRE tunnel configuration CLI commands for IPv6 tunnels.
