VRRP and VRRPE parameters 17 TABLE 88 VRRP and VRRPE parameters (Continued) Parameter Description Default See page... Router type Whether the router is an Owner or a Backup. • Owner (VRRP only) - The router on which the real IP address used by the VRID is configured. • Backup - Routers that can provide routing services for the VRID but do not have a real IP address matching the VRID. VRRP - The Owner is always the router that has the real IP address used by the VRID. All other routers for the VRID are Backups. VRRPE - All routers for the VRID are Backups. page 460 page 462 Backup priority A numeric value that determines a Backup's preferability for becoming the Master for the VRID. During negotiation, the router with the highest priority becomes the Master. • VRRP - The Owner has the highest priority (255); other routers can have a priority from 3 - 254. • VRRPE - All routers are Backups and have the same priority by default. If two or more Backups are tied with the highest priority, the Backup interface with the highest IP address becomes the Master for the VRID. VRRP - 255 for the Owner; 100 for each Backup VRRPE - 100 for all Backups page 460 page 462 Suppression of RIP advertisements A router that is running RIP normally advertises routes to a backed up VRID even when the router is not currently the active router for the VRID. Suppression of these advertisements helps ensure that other routers do not receive invalid route paths for the VRID. Disabled page 464 Hello interval The number of seconds between Hello messages from the Master One second to the Backups for a given VRID. The interval can from 1 - 84 seconds. page 464 Dead interval The number of seconds a Backup waits for a Hello message from the Master for the VRID before determining that the Master is no longer active. If the Master does not send a Hello message before the dead interval expires, the Backups negotiate (compare priorities) to select a new Master for the VRID. Three times the Hello page 464 Interval plus one-half second Backup Hello interval The number of seconds between Hello messages from a Backup to the Master. The message interval can be from 60 - 3600 seconds. You must enable the Backup to send the messages. The messages are disabled by default on Backups. The current Master (whether the VRRP Owner or a Backup) sends Hello messages by default. Disabled 60 seconds when enabled page 465 Track port Another device port or virtual interface whose link status is tracked by the VRID's interface. If the link for a tracked interface goes down, the VRRP or VRRPE priority of the VRID interface is changed, causing the devices to renegotiate for Master.
