Your Virtual link is not working. Cuz on R1, you also need the command ' area
12 virtual-link 192.168.2.2 authentication message-digest' as on the R2.
area 0 authentication message-digest only work for the whole area 0 but which
is still different from the virtual link authentication. You can check whether
I am right by "show ip ospf virtual-link" for if the virtual link status is
full.
Why I said so is also cuz: from the
R1#sh ip ro | inc 172.29.100.0
O IA 172.29.100.0/24 [110/65] via 172.29.12.2, 00:09:13,
If the Virtual link is working, the status of this route should be O but not O
IA cuz the R1 were to be pulled into area 0.

Dear All,
I had configured OSPF virtual link as below:
(f1/0) ---R1(f0/0)-------(e0/0)R2 ---- (s0/0)
(lo0) ----| | ---- (lo0)
R1 lo0: 192.168.1.1/32
R1 f1/0: 172.29.10.1/26
R1 f0/0: 172.29.12.1/26
R2 lo0: 192.168.2.2/32
R2 e0/0: 172.29.12.2/26
R2 s0/0: 172.29.100.2/29
Between R1-R2 running OSPF Area 12, Area 2 on R2 lo0, Area 1 on R1 lo0.
Redistribute R1 f1/0 to OSPF.
R1#sh run | begin router ospf

Why I can't see 192.168.1.1 in R2 routing table?
The virtual link already up.
TIA.
