Greetings everyone, Scenario: 2 CECs each with one z/VM 5.1 LPAR. Each z/VM LPAR has one TCPIP stack, MPROUTE, two OSA Expresss and one QDIO guest LAN. The Guest LANs are defined with the same subnet, lets say 10.10.10. CEC 1s Guest LAN gateway address is .1 (dot one) and CEC 2s is .2 (dot two) When TCPIP on CEC 1 is activated connectivity to the Guest LAN works fine. When TCPIP on CEC 2 is activated, I can connect to the stack, but not to the Guest LAN and connectivity to the Guest LAN on CEC 1 is gone. When I shut down CEC 2s TCPIP, connectivity returns to CEC 1s Guest LAN.
Can someone explain why this does not work and which protocol or law Im violating here? Note: I know VSWITCH is a better way to go and Im looking into using it. TIA Bob Robinson Senior Technical consultant National City Corporation
