31 Configuring additional VRRP and VRRPE parameters Dead interval The Dead interval is the number of seconds a Backup waits for a Hello message from the Master before determining that the Master is dead. When Backups determine that the Master is dead, the Backup with the highest priority becomes the new Master. The Dead interval can be from 1 - 84 seconds. The default is 3.5 seconds. This is three times the default Hello interval (1 second) plus one-half second added by the router software. The software automatically adds one-half second to the Dead interval value you enter. To change the Dead interval on a Backup to 30 seconds, enter the following commands. Router2(config)#inter e 1/5 Router2(config-if-1/5)#ip vrrp vrid 1 Router2(config-if-1/5-vrid-1)#dead-interval 30 Syntax: dead-interval The syntax is the same for VRRP and VRRPE. Backup Hello message state and interval By default, Backup do not send Hello messages to advertise themselves to the Master. You can enable these messages if desired and also change the message interval. To enable a Backup to send Hello messages to the Master, enter commands such as the following. PowerConnect(config)#router vrrp PowerConnect(config)#inter e 1/6 PowerConnect(config-if-1/6)#ip vrrp vrid 1 PowerConnect(config-if-1/6-vrid-1)#advertise backup Syntax: [no] advertise backup When you enable a Backup to send Hello messages, the Backup sends a Hello messages to the Master every 60 seconds by default. You can change the interval to be up to 3600 seconds. To do so, enter commands such as the following. PowerConnect(config)#router vrrp PowerConnect(config)#inter e 1/6 PowerConnect(config-if-1/6)#ip vrrp vrid 1 PowerConnect(config-if-1/6-vrid-1)#backup-hello-interval 180 Syntax: [no] backup-hello-interval The parameter specifies the message interval and can be from 60 - 3600 seconds. The default is 60 seconds. The syntax is the same for VRRP and VRRPE. Track port You can configure the VRID on one interface to track the link state of another interface on the Layer 3 Switch. This capability is quite useful for tracking the state of the exit interface for the path for which the VRID is providing redundancy. Refer to "Track ports and track priority" on page 1105. To configure 1/6 on Router1 to track interface 2/4, enter the following commands. Router1(config)#inter e 1/6 Router1(config-if-1/6)#ip vrrp vrid 1 Router1(config-if-1/6-vrid-1)#track-port e 2/4 1118 PowerConnect B-Series FCX Configuration Guide 53-1002266-01
