Darren still had the two interfaces plumbed in the global zone in that case as well. When the new zone with its VNIC configured on the same subnet, he could see two replies coming from that zone. This is expected since two broadcast ICMP messages will be sent in this case from the sending zone through its two ills and corresponding VNICs, and the non-global zone will reply to both ICMP requests. >> If the multiple VNICs are plumbed from different zones or VMs, then >> this additional outbound IP duplication of broadcast packets will not >> occur. > > That's not what it seems to say in the CR. If you mean specifically about the example in Entry 2 of the description, I could not duplicate that particular problem. We also confirmed using Darren's machine that when pinging from the non-global zone, only one reply was received from each VNIC on the etherstub. According to Darren the dups in Entry 2 are probably due to copy-paste from the wrong window or other mistype in bugster. That entry should be fixed to avoid further confusion.
