 Description   

I used https://jenkins.opendaylight.org/integration/job/integration-master-project-centralized-integration/2759/
Revision: 6c2498ed5e23c7ff0f6f5d9e243f450c7e37c817

Deployed as a 3 node cluster on 10.25.2.9 , 10.25.2.10 , 10.25.2.11

  1. system:property shard.persistent ${PERSISTENCE}
    PERSISTENT="false"
  1. module-shards.conf,
    REPLICA="single"

On a separate machine at 10.25.2.12 I created PCEP session with the tool here:

https://wiki.opendaylight.org/view/BGP_LS_PCEP:Testing_components#pcep-pcc-mock

java -jar pcep-pcc-mock-0.3.2-SNAPSHOT-executable.jar --log-level DE --local-address 10.25.2.12 --remote-address 10.25.2.9 --pcc 1 --lsp 100

  1. Result
    All 100 LSPs were displayed in the operational datastore at 10.25.2.9.
    localhost/restconf/operational/network-topology:network-topology/topology/pcep-topology-1

I then restarted the session.

java -jar pcep-pcc-mock-0.3.2-SNAPSHOT-executable.jar --log-level DE --local-address 10.25.2.12 --remote-address 10.25.2.9 --pcc 1 --lsp 100

I checked the restconf interface at:

localhost/restconf/operational/network-topology:network-topology/topology/pcep-topology-1

  1. Result
    No lsps were shown but the karaf log shows they were established.

{
"topology": [
{
"topology-id": "pcep-topology-1",
"topology-types": {
"network-topology-pcep:topology-pcep": {}
}
}
]
}

This warning was seen in logs

I installed the odl-bgpcep-all and tried to run the pcc-mock and I see the following error,

I checked iptables and I do not have port 4189 blocked or anything. What am I missing?

I have seen this a few times, and everytime it turned out that local IP used (10.194.126.49 in your case) belongs to a different machine.
Note that pcc-mock increases local address for each additional pcc mocked, so you need address range to accomodate pccs.

In any case, I suggest running pcc-mock on the same VM as ODL, and use 127.0.0.1 as both local and remote address.
