VPS Migration with OSPF

Postby hrdedicated » Sat Jun 01, 2013 7:48 am

Hello,

Install the Quagga routing suite available on the official website. For many distributions, a prebuilt package is available:

Under Debian:

apt-get install quagga


Under Gentoo:

emerge quagga



Under Fedora:

yum install quagga



Quagga configuration

In /etc/quagga/zebra.conf just put a password to be able to access the telnet interface.

password zebra



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 container.

Quote
password zebra
!
router ospf
redistribute kernel route-map only-ve
network YOUR_NETWORK/XX area 0.0.0.0
!
route-map only-ve permit 10
match interface venet0
!
line vty


Usage

Once your OpenVZ server takes part in the OSPF network, you can easily use the ‘vzmigrate’ command to migrate a container between different subnet of the network and the IP of the container will be redistributed in the whole network as a /32 (host route).

Thank you
