OSPF Hello subsecond timer
Closed, ResolvedPublicFEATURE REQUEST


FRR has command ip ospf dead-interval minimal hello-multiplier <1-10> under interface configuration mode.
When this command specified, then the dead-interval is set to 1 second and one must specify a hello-multiplier. The hello-multiplier specifies how many Hellos to send per second, from 2 (every 500ms) to 10 (every 100ms).
It would be great to implement this command in VyOS.
For exapmle
set interfaces <inttype> <intname> ip ospf dead-interval minimal hello-multiplier <2-10> (The value 1 doesn't make sense because in this case the hello and dead intervals are the same)

Is it a breaking change?
Perfectly compatible

Event Timeline

New syntax could be set protocols ospf interface eth0 dead-hello-multiplier <1-10> to not have to many nesting levels. Would that work out, too?

FRR only allows either
ip ospf dead-interval 4
ip ospf dead-interval minimal hello-multiplier 10
