[[Category:Networking]]
This article presents how to be able to migrate a VE container between different subnets in the network by using a dynamic routing protocol such as OSPF. An already working OSPF setup is mandatory, this article only shows the OpenVZ specifics.
== Quagga installation ==
</pre>
In /etc/quagga/ospfd.conf configure the OSPF network and area in which is OpenVZ server will be and configure the redistribution of routes generated by the VEcontainer.
<pre>
== Usage ==
Once your OpenVZ server takes part in the OSPF network, you can easily use the ‘vzmigrate’ command to migrate a VE container between different subnet of the network and the IP of the VE container will be redistributed in the whole network as a /32 (host route).
== Bugs ==
To avoid problems with this setup the IP addresses of your VE container must be taken outside of any other subnet configured on your network. If the IP address of the VE container is taken from an actual subnet, the other hosts of the subnet won't be able to communicate with it, except if you use proxy arp on the router.
