...th IPv6 and not have stray IPv4 functions messing with me. So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have NETWORKING_IPV6=yes. In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on it (have IPV6INIT=yes and IPV6_AUTOCONF=yes). But lo had IPv4. So I commented out all of the IPV4 lines in ifcfg-lo. Still have IPv4 on lo. How do I disable that? Yes, I did an service network restart after changing ifcfg-lo.

Some of the Red Hat Enterprise Linux servers in our environment sometimes get assigned virtual IP addresses (eth0:1, eth0:2, etc). Puppet Dashboard''s parameters seem like an ideal way to define and provision virtual IPs on these servers. One could create a "vip1" parameter on a node, and define a value of the IP address to use for that vip. A manifest could then be written to

...in ifcfg-eth0, and the IPv6 via RA (I set the MAC so I get an IPv6 addr that I like). I just moved the host to a network that supports static IPv4, but only dymanic IPv6, so at this time (until I get static IPv6), I need to disable the global IPv6 addressing. So in the ifcfg-eth0 file I set: IPV6INIT="no" But I am still getting a global IPv6 (and of course local scope). What else do I need to do to disable the listening for RA announcements and setting an IPv6 global address? I do not want to reboot the box. I can restart the network as needed. I seem to recall, once upon atime...

In honor of Xen Doc Day, I've put up some basic HOWTOs for setting up bridging on CentOS 6 and 7. I'm far from an expert, so I'd appreciate any feedback.

Running that ping6 command says the network can't be reached. I have to take the interface down and rerun those above commands manually. I'd appreciate any suggestions....
