Subscriber-to-Subscriber Traffic
Subscriber-to-subscriber traffic (hairpinning) refers to forwarding a packet received on
the subscriber Ethernet port to another subscriber in the same sector. Subscribers do
not communicate directly and all communication is controlled by the sector controller.
Unicast packets received from subscribers are always forwarded (reflected) unmodified
by the sector controller. Multicast or broadcast packets from subscribers are forwarded
(reflected) by the sector controller unmodified only if the 'SS to SS Broadcast/Multicast
Enable' is enabled in the associated Service Group.
