BR1 and R2 are in different IS-IS levels.

CR1 and R2 have different interface parameters.

DR1 and R2 are configured for different areas.

Answer : C

Question 7

What are three reasons a router would send out an IS-IS link-state PDU? (Choose three.)

AA new external route is imported from BGP.

BThe router's link to a neighbor goes down.
