[c-nsp] clear ip ospf redistribution

[h bagade]

Hi all,

what does this command do exactly and in which situations we should use it?
As I noticed, when we use the command, all routes which were previously
distributed via redistribution commands, will be announced as withdrawn and
after 30 mins they will be announced again!
Is this 30mins related to a relative timer which can be adjusted or it is
just fixed on 30mins?
I  would be graceful to hear your ideas and comments on this command.
