The primary link is considered to be disconnected when there is no validroute to any of the monitored network segments in a dynamic route backupgroup.Example # Create dynamic route backup group 1 to monitor routes to the networksegments 20.0.0.0/8 and 30.0.0.0/8. system-view[Sysname] standby routing-rule 1 ip 20.0.0.1 255.0.0.0[Sysname] standby routing-rule 1 ip 30.0.0.1 255.0.0.0standby timer routing-disableSyntax standby timer routing-disable secondsundo standby timer routing-disableView Interface viewParameter seconds: Delay between primary link connection and backup link disconnection,ranging from 0 to 65,535 in seconds.Description Use the standby timer routing-disable command to configure the delaybetween primary link connection and backup link disconnection. .Use the undo standby timer routing-disable command to restore thedefault.By default, the delay between primary link connection and backup linkdisconnection is 20 seconds.Example # Set the delay between primary link connection and backup link disconnection to5 seconds on Bri 3/0. system-view[Sysname] interface bri 3/0[Sysname-Bri3/0] standby timer routing-disable 5
