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
  router ospf 1
   log-adjacency-changes
   area 0 authentication message-digest
   area 12 virtual-link 192.168.2.2 message-digest-key 1 md5 cisco
   redistribute connected subnets route-map fa1
   network 172.29.12.0 0.0.0.63 area 12
   network 192.168.1.1 0.0.0.0 area 1

  router ospf 1
   log-adjacency-changes
   area 0 authentication message-digest
   area 12 virtual-link 192.168.1.1 authentication message-digest
   area 12 virtual-link 192.168.1.1 message-digest-key 1 md5 cisco
   network 172.29.12.0 0.0.0.63 area 12
   network 172.29.100.0 0.0.0.7 area 0
   network 192.168.2.0 0.0.0.255 area 2
   distance ospf inter-area 112 external 114

  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,
  FastEthernet0/0
  R1#sh ip ro | inc 192.168.2.2
  O IA 192.168.2.2 [110/2] via 172.29.12.2, 00:09:23, FastEthernet0/0
  R1#

  R2# sh ip ro | inc 172.29.10.0
  O E2 172.29.10.0/24 [114/20] via 172.29.12.1, 00:08:44, Ethernet0/0
  R2#sh ip ro 192.168.1.1
  % Network not in table

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

  TIA.
