RE: FRTS

Mohan,

Both are valid. The second implies that for all adjacencies in area 1, use
the plain-text password CISCO. However, with the wording of "between R1 and
SW1", method 1 of interface level authentication is more correct.

Interface level, being more specific will override the global options selected
as well.

Team,
If the question says the below one ..

Configure OSPF area 17 on the Ethernet segment between R1 and SW1.
 Authenticate this adjacency using the clear-text password CISCO.

The connection is R1(fa0/0)---SW1(fa1/1) ... Please advise which one we have
to use in lab ??

As per my understanding .. Method 1 :

R1

----
router osp 1
net x.x.x.x 0.0.0.0 a 17
int fa0/0
ip  osp authentication
ip osp authentication-key CISCO
SW1
------
router osp 1
net x.x.x.x 0.0.0.0 a 17
int fa1/1
ip  osp authentication
ip osp authentication-key CISCO
Method 2 :
R1
router osp 1
area 17 authentication
int fa0/0
ip  osp authentication-key CISCO
SW1
router osp 1
area 17 authentication
int fa1/1
ip osp authentication-key CISCO
