A new service provider asked you to design its IS-IS network. You determined that two distinct IS-IS areas will
be required and you must now create an ISO addressing plan for the participating intermediate systems
(routers).
In this scenario, which two statements are correct? (Choose two.)
A.
The NET addresses can be configured on any interface.
B.
The NET addresses must be configured on the loopback interface.
C.
The system ID within the NET address must match for all intermediate systems within the same area.
D.
The system ID within the NET address must unique for all intermediate systems within the same area.
Explanation:
IS-IS uses ISO network addresses. Each address identifies a point of connection to the network, such as arouter interface, and is called a network service access point (NSAP).
The system identifier must be unique within the network.
