Referring to the diagram and configuration on Routers XR-1 and XR-2, which three statements are correct? (Choose three.)
A. Router XR-1 can never be a designated router or designated intermediate system.
B. The transmission of IS-IS packets will be suppressed on interface GigabitEthernet0/0/0/2 on Router XR-1.
C. The received IS-IS packets from Router XR-2 will be suppressed from being processed.
D. Router XR-1 and Router XR-2 will form a neighbor adjacency, and Router XR-2 will become the designated router or designated intermediate system.
E. Router XR-1 will use the incremental shortest path first algorithm when there are minimal topology changes.
F. Router XR-1 can form a neighbor adjacency over interface GigabitEthernet0/0/0/2 but will not advertise 10.1.1.0/24 in its link-state packets (LSPs).
