Piotr, that he does not wants to do (he needs to do it on more routers).
I have also misread the post the first time.
Ok, Sergei, here are the options in my opinion:
1. Redistribute connected, effectively making router an ASBR. Then use
"summary-address not-advertise" option
i.e.*
router ospf 1
redistribute connected subnets
summary-address 1.1.1.0 255.255.255.0 not-advertise
*
2. Redistribute connected using E1 metric, set the metric to nearly maximum
value. i.e.
(out of my head, not for copy-pasting of course)
route-map TRICK
match interface lo0
set type E1
set metric to about maximum -5
router ospf 1
redistribute connected subnets
