There was a discussion about the same scenario within the last fortnight.
You can find them in the archive.
I believe this issue is related to the IOS versions. The best way to choose
either R1 or R2 to get to BB1 and BB3 routes from R5 is to modify the cost
from R2 or summarization at R2.

Subject: OSPF distance command affecting all routes ignoring the source
address
The following are configured on R5 to decrease the distance to
139.1.0.0received from
150.1.2.2
access-list 1 permit 139.1.0.0
distance 109 150.1.2.2 0.0.0.0 1
However, R5 would decrease the distance for the route received from
150.1.1.1 also.
See below
Before the distance command
O IA 139.1.0.0/24 [110/129] via 139.1.25.2, 00:00:01, Serial0/0/0.52
[110/129] via 139.1.15.1, 00:00:01, Serial0/0/0.51
After the distance command
O IA 139.1.0.0/24 [109/129] via 139.1.25.2, 00:00:02, Serial0/0/0.52
[109/129] via 139.1.15.1, 00:00:02, Serial0/0/0.51
The OSPF database below shows that the router ID is correct.
Summary Net Link States (Area 1)
Link ID ADV Router Age Seq# Checksum
139.1.0.0 150.1.1.1 751 0x80000002 0x009143
139.1.0.0 150.1.2.2 710 0x80000006 0x007C52
