Description of problem: Feature request. For IPv4, we can specify ranges like : /etc/sysconfig/network-scripts/ifcfg-ethX-range0 CLONENUM_START=0 DEVICE=eth0:0-253 IPADDR_START=x.x.1.1 IPADDR_END=x.x.1.254 NETMASK=255.255.255.0 Would be very useful to be able to do something similar for IPv6. Since network-scripts/ifup-ipv6 and network-scripts/network-functions-ipv6 are based on http://www.deepspace6.net/projects/initscripts-ipv6.html, this could probably be easily implemented based on (ipv6_add_addr_on_device_with_range_support) : * http://cvs.deepspace6.net/view/*checkout*/initscripts-ipv6/common/etc/sysconfig/network-scripts/network-functions-ipv6 * http://cvs.deepspace6.net/view/*checkout*/initscripts-ipv6/common/etc/sysconfig/network-scripts/ifup-ipv6 Second feature request regarding IPv6 secondaries would be to be able to set the preferred_lft to something custom, eg : ipv6_exec_ip addr change $ipv6addr dev $DEVICE preferred_lft 0 So you can prevent the addresses from being included in the source address selection algorithm. (Based on http://www.davidc.net/networking/ipv6-source-address-selection-linux, and it works ok) Debian & Gentoo seem to support this via their config files. Version-Release number of selected component (if applicable): initscripts-9.03.4-1.el6.i686
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion.
There's a bug already on preferred_lft, actually.
Sorry, you're totally right. I missed that one (Bug #583441).
This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. **
If this is denied for 6.0, could this be considered for 6.1 then please ?
Since RHEL 6.3 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
I am closing this as wontfix, this RFE is quite old and we don't have a patch for it (original links does not work anymore). If somebody still wants this feature, please feel to reopen this bug.
We'd appreciate to get a way that at least IPv6-secondaries can be declared as "preferred_lft 0" (not to be used for automatic source-selection) in ifup-ipv6. See also #583441 filed against Fedora.
