OSPF flood reduction and stable topology

    Hi everyone,

    We have a lot of spokes sites that are on SAT COM , if spokes goes down and stays down for over 1 hr, all LSA on spoke site get aged out.  This will result in longer time for spoke site to be full functional ( OSPF LSA are exchanged over small BW  long latency SAT COM CKT ,  greater the number of LSA , longer it takes for spoke site to  reach " Full"  OSPF  neighbor state).

    I  did some testing with OSPF flood reduction that literally shaves off 20 seconds for my spoke sites to reach OSPF full state in my lab testing.

    My question to community is   have you guys encountered any issues when  using OSPF flood reduction in your production network?

    Much appreciated!!
