What I meant was that the v6 address changed, not the MAC. Actually, a little more lookin' has shown that it DOESN'T always change. (I thought I say it before...)
Here's eth0 and eth1 from guest1: 4: eth1: <BROADCAST,MULTICAST,UP> mtu 1492 qdisc pfifo_fast qlen 100 link/ether 00:02:55:9a:b9:ca brd ff:ff:ff:ff:ff:ff inet 10.14.3.30/24 brd 10.14.3.255 scope global eth1 inet6 fe80::2:5500:9a:b9ca/64 scope link 5: eth0: <BROADCAST,MULTICAST,UP> mtu 1492 qdisc pfifo_fast qlen 100 link/ether 00:02:55:9a:b6:93 brd ff:ff:ff:ff:ff:ff inet 10.14.3.29/24 brd 10.14.3.255 scope global eth0 inet6 fe80::2:55de:309a:b693/64 scope link And here's eth0 and eth1 from guest2: 4: eth1: <BROADCAST,MULTICAST,UP> mtu 1492 qdisc pfifo_fast qlen 100 link/ether 00:02:55:9a:b9:ca brd ff:ff:ff:ff:ff:ff inet 10.14.3.27/24 brd 10.14.3.255 scope global eth1 inet6 fe80::2:5500:9a:b9ca/64 scope link tentative 5: eth0: <BROADCAST,MULTICAST,UP> mtu 1492 qdisc pfifo_fast qlen 100 link/ether 00:02:55:9a:b6:93 brd ff:ff:ff:ff:ff:ff inet 10.14.3.26/24 brd 10.14.3.255 scope global eth0 inet6 fe80::2:5500:9a:b693/64 scope link Notice that the inet6 addrs for eth0 are different, but they are the same for eth1. This is after a reipl of each guest and each guest is running within the same VM LPAR. I did receive the duplicate message in the eth1 case. The error occurs right after this command (from ifup) is ussed: ip link set up dev eth1 mtu 1492 Thanks much, Leland CONFIDENTIALITY NOTICE: This e-mail communication and any attachments may contain confidential and privileged information for the use of the designated recipients named above.
