OSPF Authentication on Virtual Link

I have a question about authentication on Virtual Link:

 

The FR cloud - Hub and Spoke: R1 (s0/0), R2 (s0/0)and R3(s0/0). R1 being
hub.

 

FR Cloud is in area 1

 

R1( S0/1)has its serial connected via p2p frame-relay circuit to r4 (s0/0).

 

R1 and R4 are in area 0

 

R3 and Sw1 are in area 3

 

 

The virtual-link is created with area 1 as transit area between r3 and r1.

 

Authentication:

 

 Area 1 - authentication clear text with pw cisco

 

Area 0 - authenticated using md5 with pw cisco

 

 

Router osp 1

 

Area 0 authentication message digest

Area 1 authentication

 

The question is for the Virtual Link: Since the Virtual interface is in
considered an area 0 interface after the virtual link is up, does it needs
to be configured with area 0 password or area 1 password?

 

Area 1 virtual link 1.1.1.1 message-digest-key 1 md5 cisco

 

Or

 

Area1 virtual link 1.1.1.1 authentication-key cisco

 

 

Thank you,

Emil
