Are you sure you can't filter the summary on the redistribution router?
How if we put route-map and restrictive access-list in redistribute igrp
command, so it only allow route from internal IGRP get into OSPF?

Nope. What happens is when you use summary address, it creates null0 route
which again is being redistributed back to OSPF as external route and it
appears on all ospf routers. You can't filter this on the redistribution
router. The solution is either filter it on each ospf router or use
'not-advertise' command.
Note that in some older IOS version 'not-advertise option wouldn't work as
I
specified above.
If you search archives, you can find a thread on this.

Thanks for the config.
router ospf 10
summary-address 147.1.20.0 255.255.255.0 not-advertise
summary-address 147.1.1.0 255.255.255.0 not-advertise
Isn't the not-advertise meant for filtering type 7 lsa when used with
summary-address ?
