Referring to the exhibit, which configuration must be set on R2 to from a Level 1 IS-IS adjacency with R1?
A.
Set interfaces lo0 unit 0 family iso address 49.0001.3415.0010.0250.0000.0046.00
B.
Set interfaces lo0 unit 0 family iso address 49.0002.3414.0010.0250.0000.0046.00
C.
Set interfaces lo0 unit 0 family iso address 49.0002.3415.0010.0250.0000.0046.00
D.
Set interfaces lo0 unit 0 family iso address 49.0001.3414.0010.0250.0000.0046.00
Why A? For me is D, in answer A AreaID does not match. If you see the exhibit Areaid: 49.0001.3414.0010, and is mandatory for L1 adjacency would be the same.
i think the right answer is D as area id must be the same to establish level 1 adjacency
