Controllers are VSWITCH managers, not general-purpose stacks. They aren't involved in VSWITCH data transfer and so their use of MPROUTE wouldn't accomplish anything except to drive the network insane. > We see the IP Addresses for the zLinux on the OSA but the network people say > they don't see the IP Addresses associated with the OSA MAC address [snip diagram] > Is this network design compatible with a zVM RIP2/MPROUTE setup? Not usually, no. If you are using a VSWITCH, then there is no virtual router. zLinux1...zLinuxn are all logically directly attached to the external network. If you are using a layer 3 VSWITCH (IP), then the zLinux IPs will be associated with the OSA MAC. If you are using layer 2 (ETHERNET), then the IPs are associated with virtual MAC addresses generated by CP. Take a look at the CP Connectivity book. If you're trying to create an "out of network" failover scenario, then you build that with a traditional virtual router. The vrouter can itself be on a VSWITCH in order to protect its paths to the physical switch.
