Quagga integrates the OSPF protocol, which allows routes to be dynamically advertised so that other machines know which path to use to reach internal networks. -------------- **Context : ** We have two routers - router-002 (BACKUP) - router-003 (ACTIVE) When a failover occurs: - CARP moves the VIP to the new ACTIVE router - The OVH script updates the MAC address T2276 Remote machines (such as Windriver, Ysul, and CloudHugger) use a GRE tunnel to reach the network 172.27.27.0/27. `When the active router changes, the previous tunnel becomes unavailable and is removed, which also deletes the associated route.` As a result, if nothing is done, these machines no longer have a valid route to reach the internal network. To solve this, the active router must advertise the network using OSPF, so that remote machines automatically learn the correct route and can continue to reach the network. ----------------------- References : https://fr.wikipedia.org/wiki/Quagga_(logiciel) https://enotepaper.wordpress.com/2014/01/08/installing-quagaa-on-freebsd/
