Virtual link is part of area 0, so when you create VL, area 1 vir
10.10.10.10 , you have to use type 1 authencation, area 1 vir 10.10.10.10
authen
area 1 vir 10.10.10.10 authen-key ....
And on the sub-interface for area 1, you can put in interface command
Ip ospf mess-key 1 md5 cisco
And under router ospf 10
Area 1 authen mess
Give it a try,
It should work,,

Subject: OSPF double authentication
Hi Group ,
Need some help here. Scenario is :
R1 has subinterfaces and point-to-point interfaces
as well.Other routers can't have subinterfaces.
R1 - R4 are in Area 0
R1 - R2
R3 are in area 1.
S0/0.1
R1-----|----FR-----R2
S0/1| |
| |----FR-----R3
FR
|
|
R4
Area 0 has to use type 1 authentication and Area 1 has
to use type 2 (MD5) authentication.In my home lab when
I created this scenario , since R1 has a single
subinterface, how do we add the authentication for
Area 1 and also authenticate the virtual link .Both
kind of authentication have to be on the same
subinterface on R1.
cheers !
Prakash SR
