Problem: A Pod in Master can ping to a node in Node, whereas trace path fails. Also, TCP connection between these pods give timeout errors.
We have below nodes NODES [root@ip-10-20-4-38 network-scripts]# oc get nodes NAME STATUS AGE master.hazelcast-ocp.com Ready 8d node1.hazelcast-ocp.com Ready 8d Master is also a node SUBNET [root@ip-10-20-4-38 network-scripts]# oc get hostsubnet NAME HOST HOST IP SUBNET master.hazelcast-ocp.com master.hazelcast-ocp.com 54.160.17.51 10.128.0.0/23 node1.hazelcast-ocp.com node1.hazelcast-ocp.com 52.205.214.205 10.129.0.0/23 PODS [root@ip-10-20-4-38 network-scripts]# oc get pods NAME READY STATUS RESTARTS AGE docker-registry-1-f9lcn 1/1 Running 1 2d hz-rc-9h10b 1/1 Running 1 15m hz-rc-fc64l 0/1 Running 0 16m router-1-pfv0f 1/1 Running 0 3h [root@ip-10-20-4-38 network-scripts]# oc describe pod hz-rc-9h10b Name: hz-rc-9h10b Namespace: default Security Policy: restricted Node: node1.hazelcast-ocp.com/52.205.214.205 Start Time: Wed, 26 Apr 2017 07:10:28 -0400 Labels: name=hazelcast-node-hz Status: Running IP: 10.129.0.61 [root@ip-10-20-4-38 network-scripts]# oc describe pod hz-rc-fc64l Name: hz-rc-fc64l Namespace: default Security Policy: restricted Node: master.hazelcast-ocp.com/54.160.17.51 Start Time: Wed, 26 Apr 2017 07:09:35 -0400 Labels: name=hazelcast-node-hz Status: Running IP: 10.128.0.100 From Master Node: [root@ip-10-20-4-38 network-scripts]# ip route get 10.129.0.61 10.129.0.61 dev tun0 src 10.128.0.1 cache [root@ip-10-20-4-38 network-scripts]# ip a show dev tun0 10: tun0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 8951 qdisc noqueue state UNKNOWN qlen 1000 link/ether e2:b5:07:a5:10:fd brd ff:ff:ff:ff:ff:ff inet 10.128.0.1/23 scope global tun0 valid_lft forever preferred_lft forever inet6 fe80::e0b5:7ff:fea5:10fd/64 scope link valid_lft forever preferred_lft forever [root@ip-10-20-4-38 network-scripts]# tracepath 10.129.0.61 1?: [LOCALHOST] pmtu 8951 1: no reply 2: no reply 3: no reply Could you please advice?
