| 68 | path-selection-group as the egress for a particular type of |
| 69 | traffic (e.g., DSCP value). The system then utilises its |
| 70 | standard forwarding lookup mechanism to select from the |
| 71 | paths that are specified within the group - for IP packets, |
| 72 | the destination IP address is used such that the packet is |
| 73 | routed to the entity within the path-selection-group that |
| 74 | corresponds to the next-hop for the destination IP address |
| 75 | of the packet; for L2 packets, the selection is based on the |
