    Hello,

    the command is used mainly to reduce the amount of traffic in an area
    caused by the flooding of LSAs. By default, OSPF floods LSAs out all
    participating interfaces (except the one from which it is learned), and
    that can cause a high load of traffic and potentially instability
    during flapping. So the command can be useful in large, fully-meshed
    OSPF environements.
    Also, the command still allows adjacencies to be established, it only
    blocks LSA advertisement...
    Does that make sense ?

    Regards,

    Naz
