Abstract
Selecting remote path using forwarding path preferences is disclosed. In an embodiment, a message of a first network node identifying one or more forwarding path preferences in association with one or more destination addresses is received at a packet router. A particular path corresponding to a particular forwarding path preference from among the one or more forwarding path preferences received in the message is determined and in response a particular label is determined. A forwarding entry associating the particular label with the particular forwarding path preference and the particular path is stored. The particular label is forwarded to a second network node. A packet including the particular label is received at the packet router and the particular path associated with the particular label included with the packet is selected based on the forwarding entry associated with the label. The packet is forwarded to a network node via the selected path.
