Configuring PCEP on a PE Router
A Path Computation Client (PCC) supports the configurations related to the Path
Computation Element (PCE) and communicates with Paragon
Automation.
However, you must configure PCEP on each PE router to configure the router as a PCC and
establish a connection between the PCC and Paragon Automation. A PCC initiates path
computation requests, which are then executed by Paragon Automation.
Configuring a PE Router as a PCC
To configure a PE router as a PCC:
Enable external control of LSPs from the PCC router to Paragon Automation.
[edit protocols] user@PE1# set mpls lsp-external-controller pccd
Specify Paragon Automation (paragon) as the PCE that the PCC connects to, and specify the Paragon Automation host external IP address as the destination address.
[edit protocols] user@PE1# set pcep pce paragon destination-ipv4-address 10.99.99.1
Configure the destination port for the PCC router that connects to Paragon Automation (PCE server) using the TCP-based PCEP.
[edit protocols] user@PE1# set pcep pce paragon destination-port 4189
Configure the PCE type.
[edit protocols] user@PE1# set pcep pce paragon pce-type active user@PE1# set pcep pce paragon pce-type stateful
To verify that PCEP has been configured on the router, open a telnet session to access the router, and run the following commands:
user@PE1> show configuration protocols mpls
Sample output:
lsp-external-controller pccd;
user@PE1> show configuration protocols pcep
Sample output:
pce paragon { local-address 10.0.0.101; destination-ipv4-address 10.99.99.1; destination-port 4189; pce-type active-stateful; lsp-provisioning; }
