  • 1.  Starting PCEP session

    Posted 05-18-2021 16:01
    I am trying to start a PCEP session with a vMX router as the PCC and an external device as the PCE.  I have set up the following configuration piece on the vMX router:
    packet@LAX-P-101> show configuration protocols pcep 
    pce 1 {
        local-address 10.74.0.101;
        destination-ipv4-address 192.168.123.67;
        destination-port 4189;
        pce-type active stateful;
        lsp-provisioning;
        traceoptions {
            file pce1;
        }
    }​

    However the session state stays in PCE_STATE_NEW without any attempt to set anything up:

    PCE 1
    --------------------------------------------
    General
        PCE IP address           : 192.168.123.67
        Local IP address         : 10.74.0.101
        Priority                 : 0
        PCE status               : PCE_STATE_NEW
        Session type             : PCE_TYPE_STATEFULACTIVE
        LSP provisioning allowed : On
        P2MP LSP report allowed  : Off
        P2MP LSP update allowed  : Off
        P2MP LSP init allowed    : Off
        PCE-mastership           : main
        PCE Traffic Steering     : Off

    Is there a command I'm missing to start the session establishment?

    Your client side configuration looks complete.  Using Northstar as a controller I have the same configuration without the lsp-provisioning flag and all is active on our client nodes.

    Check your controller status and logs.

    On the client see if there are clues in these

    show path-computation-client active-pce
    show path-computation-client status extensive

    I am not seeing anything being sent to my PCE from PCC at all.

    This seems the controller is not communicating with the client request, are there logs on your controller to check?

    Or do you have a protect re firewall filter applied on the client that is blocking communications?

    A tcpdump on the PCE does not show any PCEP Open messages being received, though the PCE does get ping messages.  Is there a way to check on vMX if any Open messages have been sent for a session?

    Are you sourcing the ping from the same address as the pcep session?
    Does ping from the controller to the pcep ip address also transit?

    Yes, ping is from the same source address:

    Looks like the issue was I had not configured pccd.  With that configured, the session starts up!
