Each guest LAN is a different LAN segment and require their own subnet.
Try 10.10.11 (assuming a 24-bit netmask) for CEC2.

Greetings everyone,
Scenario:
2 CEC’s each with one z/VM 5.1 LPAR. Each z/VM LPAR has one TCPIP stack,
MPROUTE, two OSA Express’s and one QDIO guest LAN. The Guest LAN’s are
defined with the same subnet, let’s say 10.10.10. CEC 1’s Guest LAN
gateway address is .1 (dot one) and CEC 2’s 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
2’s TCPIP, connectivity returns to CEC 1’s Guest LAN.
Can someone explain why this does not work and which protocol or law I’m
violating here?
Note: I know VSWITCH is a better way to go and I’m looking into using it.
TIA
