Virtual Router Redundancy Protocol is an election protocol that provides high availability.
A number of servers may participate in one or more virtual services. One or more IP addresses - and mac adresses - may be assigned to a virtual group.
After many versions, it's time to take stock of Vrrpd
Vrrpd include now:
- VRRPD - when an interface change his state to backup, or master, them can have associated up/down scripts
- VRRPD - Ethtool supervision (link up/down)
- VRRPD - multi-interfaces - The Master communicate his state to all another process. If for some reason one process be backup, link down for example, all the system change for backup state.
- VRRPD - Magic packet - If you can't use virtual mac adress, Vrrpd send gratuitous ARP and it can also send magic packet from virtual to gateway
- VRRPD - Is now Compatible with vlan interfaces - with one vmac by vlan -
- Atropos client - You can use atropos for change or/and know the master's state (for example in supervision script)
Vrrpd est maintenant directement compatible avec les interfaces de type vlan.
De plus si vous n'utilisez pas la mac virtuelle il existe une nouvelle fonctionnalité permettant de rafraichir la table ARP en envoyant un paquet depuis l'IP virtuelle vers une destination de son choix.
Merci à Pascal pour le paquet Debian.
