Supported Features for MLPPP LNS and PPPoE Subscribers

Subscribers to multilink PPP (MLPPP) for L2TP network server (LNS) or to Point-to-Point Protocol over Ethernet (PPPoE, terminated and tunneled) can access a variety of new features.

  • Supports MLPPP for static and dynamic LNS subscribers and PPPoE subscribers.

  • Supports each MLPPP bundle containing a single member link.

  • Anchors the bundle logical interface (IFL) on the inline services si interface.

  • Runs the bundle IFL on a router that enables shaping and queuing at the bundle to minimize fragment reordering.

  • Supports configurable service device pools for load-balancing bundle IFLs.

  • Supports the co-existence for member link IFL and the bundle IFL on different lookup engines.

  • Supports fragmentation maps for both static and dynamic si interfaces, and supports multiple forwarding classes pointing to a single queue for si interface attachments.

  • Provides fragmentation of low-priority packets towards the subscriber, and reassembly of low-priority packets towards the core, and availability of per-bundle fragmentation and reassembly statistics.

  • Supports bundle family inet and family inet6, including DHCPv6 prefix delegation over MLPPP bundle for both LNS and PPPoE MLPPP subscribers.

  • Supports lawful intercept over MLPPP bundles.

  • Provides mixed mode (PPP and MLPPP) support for subscribers.

  • Maintains existing LNS and PPPoE subscriber management functionalities.

  • Supports graceful Routing Engine switchover (GRES).
