Configuring the Automatic SR-TE Tunnel Capability on a PCC

Configuring the Automatic SR-TE Tunnel Capability on a PCC

The PCE Initiated LSP protocol needs to be configured for automatic RSVP-TE tunnels. A controller runs this protocol to deliver tunnel and path information to the ingress on which a forwarder resides. Upon receipt of the information, the ingress automatically establishes an RSVP-TE tunnel.


The PCE Initiated LSP protocol is used to implement the automatic RSVP-TE tunnel function. A PCE client (PCC) (ingress) establishes a PCE link to a PCE server (controller). The controller delivers tunnel and path information to a forwarder configured on the ingress. The ingress uses the information to automatically establish a tunnel and reports LSP status information to the controller along the PCE link.
