This will of course summarize 172.10 routes in area non-zero, which this ABR will then advertise into Area 0, where all other ABRs will receive and advertise that same type 3 LSA into their non-area 0 areas.
So, the summarization is done in the ABR connected to the non-zero area containing the prefixes you wish to summarize.
I don't know any other way to accomplish this.

I want to filter all of /30 prefix in ABR from advertised from area 0 to non-area0. But i cannt figure how to do it.
in cisco, the config is something like:
router ospf ...
area 100 filter-list prefix NO30 in
ip prefix-list NO30 seq 10 deny 0.0.0.0/0 ge 30 le 30
