rtg Dpn Forwarding Policy

This attribute specifies the forwarding policy used by packet forwarding to handle DPN traffic on a Passport module. When this attribute is set to loadshare, DPN traffic is shared among preferred links in a link group in proportion to the available bandwidth on each link; the traffic is not forwarded in an order- preserved manner and needs resequencing at the destination, but the available bandwidth in a link group is utilized efficiently. When this attribute is set to loadspread, DPN traffic is forwarded in an order-preserved manner along a randomly selected route; the traffic sticks to a particular link in a link group, and will not spill over to other links in the link group unless there is congestion on the selected link. When this attribute is set to loadspreadFast, DPN traffic is forwarded in an order-preserved manner along a randomly selected route; the traffic sticks to a particular link in a link group, and will not spill over to other links in the link group. Choosing this value may improve throughput but traffic may be discarded in the presence of congestion. It is recommended that all nodes in the network be provisioned with the same forwarding policy.
