Hi, I've got 2 questions about VRRP routers *ownership *handling in Keepalived: According to the VRRP RFCs, an owner router must assert its priority to 255 in order to preemt and become the Master as soon as it is up. RFC 5798, section 5.2.4: "The priority value for the VRRP router that owns the IPvX address associated with the virtual router MUST be 255 (decimal)." 1) Keepalived - it was possible for me to configure an owner VRRP router and assign it a value less then 255. When the router was up, a priority value of 255 was not asserted automatically and it was not elected as a MASTER (of course preemption was enabled). Is it OK to successfully load a configuration in which a VRRP owner router has a priority less then 255? Is it OK that priority value of 255 is not asserted on run-time for VRRP owners? 2) Should Keepalived update VRRP routers ownership automatically? For example: 2.1) IP addition: Assuming a non-owner VRRP router is configured on a link. A new real IP is added on the link and this IP equals one of the VIPs assigned to the VRRP router on that link. Would that router will be updated automatically with a priority value of 255? 2.2) IP deletion: Assuming an owner VRRP router is configured on a link. A real IP which is the last one owned by a VRRP router is removed on a link and makes the router a NON owner router. Would a priority value of 255 be released, in case it was previously asserted to 255 for ownership? Alexandre, I do keep in mind your clear statement that "this mailing list is not a ticketing tracking system". There are still some things we find important to ask, we will be very thankful to have answers and to contribute if possible.
