Default ch9 -- show ip ospf database - 7th ed.

I followed the OSPF settings closely, but i don't understand why on page 469, the database net link output shows this in the book (red)...my output is below in (blue)

book:
Net Link States (Area 0)
Link ID ADV Router Age Seq# Checksum
10.1.5.1 10.1.5.1 491 0x80000002 0x000c57



my net link output shows:

Net Link States (Area 0)
Link ID ADV Router Age Seq# Checksum
10.1.5.2 172.16.10.1 491 0x80000002 0x000c57


---------------------------------------------------------


CORP#show ip ospf database
OSPF Router with ID (10.1.5.1) (Process ID 132)
Router Link States (Area 0)

Link ID ADV Router Age Seq# Checksum Link count
10.1.5.1 10.1.5.1 83 0x8000000c 0x00feff 8
172.16.10.1 172.16.10.1 491 0x80000006 0x00feff 2
192.168.20.1 192.168.20.1 490 0x8000000d 0x00feff 6
192.168.40.1 192.168.40.1 84 0x80000005 0x00feff 4

Net Link States (Area 0)
Link ID ADV Router Age Seq# Checksum
10.1.5.2 172.16.10.1 491 0x80000002 0x000c57



-----------------------------------
also - in the book, the router R3 network statement is:

r3...router ospf 132
r3...network 10.1.5.2 0.0.0.0 area 0

why is r3's network statement different from R1 & R2's network statements?

r1...router ospf 132
r1...network 10.1.2.0 0.0.0.255 area 0
r1...network 10.1.3.0 0.0.0.255 area 0

Thanks,
Pcameron1
