=== Preparations ===
You not only need to [[Installation | install]] the crtools, but also check that the iproute2 utility (<code>ip</code>) is not v3.
5. 1 or earlier.
Since v3.5.2 is not yet released (as per 20 Sept 2012), you should compile it from [http://git.kernel.org/?p=linux/kernel/git/shemminger/iproute2.git;a=summary sources]. In order to tell to crtools where the proper ip tool is set the <code>CR_IP_TOOL</code> environment variable.
=== Dump and restore ===
