"A path selection group is a set of forwarding resources,
which are grouped as eligible paths for a particular
policy-based forwarding rule. A policy rule may select a
path-selection-group as the egress for a particular type of
traffic (e.g., DSCP value). The system then utilises its
standard forwarding lookup mechanism to select from the
paths that are specified within the group - for IP packets,
the destination IP address is used such that the packet is
routed to the entity within the path-selection-group that
corresponds to the next-hop for the destination IP address
of the packet; for L2 packets, the selection is based on the
destination MAC address. If multiple paths within the
selection group are eligible to be used for forwarding,
the packets are load-balanced between them according to
the system's usual load balancing logic.";
