You need area 0 authentication on R2 as well and take out "area 1
virtual-link 202.97.2.2 authentication message-digest" , you dont need this.

area 1 virtual-link 202.97.2.2 authentication message-digest
area 1 virtual-link 202.97.2.2 message-digest-key 1 md5 cisco
...
R2:
router-id 202.97.2.2
area 1 authentication message-digest
area 1 virtual-link 202.97.1.1 authentication message-digest
area 1 virtual-link 202.97.1.1 message-digest-key 1 md5 cisco
