+          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.";
