Refer to the Exhibit
The 10.200/16 network is announced as an IS-IS route by R2 to its IS-IS neighbors. R3 and R4 are configured with an IS-IS export policy, which announces this route to R5 and R6. Which statement is true?
A.
When viewed on R5 the 10.200/16 route will be marked down.
B.
When viewed on R5 the 10.200/16 route will be marked up.
C.
The 10.200/16 route will not be visible on R5.
D.
The 10.200/16 route will be marked with the overload bit.
Correct answer is B. ISIS set the U/D bit when leaking routes from L2 to L1
Sorry, I meant the opposite. Correct Answer is A. The confusion comes from the fact that is marked UP when the bit is set to 0 and it is marked us DOWN when it is set to 1.
