ip ospf hello-interval

ip ospf hello-interval
Configures the hello interval.
Synopsis ip ospf hello-interval interval
no ospf hello-interval
Operands interval Hello interval in seconds.
Defaults The default value is 10 seconds.
Command Modes Interface subtype configuration mode
Description Use this command to set the length of time between the transmission of hello packets that this
interface sends to neighbor routers. If you change the hello interval, the dead interval is changed
to be four times the new hello interval, unless the dead interval is also explicitly configured using
the ip ospf dead-interval command. Also, running-config displays only explicitly configured values
of the dead interval, which means that a value that got automatically changed as the result of a
hello-interval change would not be displayed.
Usage Guidelines Enter no ospf hello-interval to use the default value.
Examples To set the hello interval to 200 on a specific OSPF 40-gigabit Ethernet interface:
switch(config)# interface fortygigabitethernet 101/0/10
switch(conf-if-fo-101/0/10)# ip ospf hello-interval 200
To set the hello interval to 180 on a specific OSPF virtual Ethernet (VE) interface:
switch(config)# rbridge-id 178
switch(config-rbridge-id-178)# interface ve 24
switch(config-ve-24)# ip ospf hello-interval 180
