Release Information

Statement introduced in Junos OS Release 19.4R1.

Description

Configure a fabric path optimization mode to optimize the fabric path of the traffic flowing over Abstracted Fabric (af) interfaces between two guest network functions (GNFs). After configuring fabric path optimization, you can use the command show interfaces af-interface-name in GNF to view the number of packets that are currently flowing on the optimal / non-optimal path.

Note
  • You must configure the collapsed-forward statement on both the peer guest network functions (GNFs) on the Abstracted Fabric interface for the commit to be successful.

  • The collapsed-forward statement is configured at the Abstracted Fabric interface level. All logical interfaces on the Abstracted Fabric interface inherit this configuration.

  • We strongly recommend that you do not configure the collapsed-forward statement on GNFs that have a mix of supported and unsupported MPCs (MPCs that support fabric path optimization and MPCs that do not) to avoid any erratic behavior.

Options

monitorIf you configure this mode, the peer GNF monitors the traffic flow and sends information to the source GNF about the Packet Forwarding Engine to which the traffic is being forwarded currently and the desired Packet Forwarding Engine that could provide an optimized path. However, the source GNF does not forward the traffic towards the desired Packet Forwarding Engine.
optimizeIf you configure this mode, the peer GNF monitors the traffic flow and sends information to the source GNF about the Packet Forwarding Engine to which the traffic is being forwarded currently and the desired Packet Forwarding Engine that could provide an optimized path. The source GNF then forwards the traffic towards the desired Packet Forwarding Engine.
