[Sysname-ospfv3-200] silent-interface vlan-interface 10 spf timers Syntax spf timers delay-interval hold-interval View undo spf timers OSPFv3 view Default level 2: System level Parameters delay-interval: Interval in seconds between when OSPFv3 receives a topology change and when it starts SPF calculation. in the range of 0 to 65535. hold-interval: Hold interval in seconds between two consecutive SPF calculations, in the range of 0 to 65535. Description Use spf timers to configure the delay interval and hold interval for OSPFv3 SPF calculation. Use undo spf timers to restore the default. The delay interval and hold interval default to 5s and 10s. An OSPFv3 router works out a shortest path tree with itself as root based on the LSDB, and decides on the next hop to a destination network according the tree. Adjusting the SPF calculation interval can restrain bandwidth and router resource from over consumption due to frequent network changes. Setting both the delay-interval and hold-interval to 0 triggers an SPF calculation at once, improving the network convergence speed. Examples # Configure the delay interval and hold interval as 6 seconds for SPF calculation. system-view [Sysname] ospfv3 1 [Sysname-ospfv3-1] spf timers 6 6 stub (OSPFv3 area view) Syntax stub [ no-summary ] View undo stub OSPFv3 area view Default level 2: System level 268
