sorry i'm still don't get it
lets say if regular update will due in 8 seconds :
Sending updates every 60 seconds, next due in 8 seconds
Flash update is suppressed when next update due within 10 seconds
and i shut/no sh my loopback interface
this debug output will not show up :
Dec 23 04:12:10.595: RIP: sending v2 flash update to 224.0.0.9 via
Loopback0 (1.1.1.1)
is that the correct result ?
because my debug output still producing that entry.
thx
