Load-balancing support for subscriber traffic on pseudowire service interface

Junos OS support load balancing for subscriber sessions on the pseudowire service interface over multiple logical tunnel child member links of a redundant logical tunnel (RLT) interface at the same time. The load balancing property of the RLT interface allows subscriber traffic on the pseudowire service interface to be dispersed and load-balanced over different PICs and line cards. Service providers can enable BNG subscriber sessions on the PS interface with the support of multiple active links. An RLT interface allows up to a maximum of 32 member LT interfaces. This redundancy protects the access and the core-facing link against anchor Packet Forwarding Engine failure across line cards.
