Typedef Documentation

Flags present on an ADJ sourced path-extension.

Flags present on an MPLS label sourced path-extension.

A path extension is a per-entry addition to the forwarding information when packets are sent for that entry over that path.

For example: ip route add 1.1.1.1/32 via 10.10.10.10 out-label 100

The out-going MPLS label value 100 is a path-extension. It is a value sepcific to the entry 1.1.1.1/32 and valid only when packets are sent via 10.10.10.10.

A description of the type of path extension.
