Which of the following descriptions about the difference between DIS in IS-IS and DR in OSPF are correct? (Multiple choice)
The correct answer is B. In the IS-IS broadcast network, routers of the same level on the same network segment will form adjacency relationships, including all non-DIS routers will also form adjacencies with each other, and the DIS will also form adjacencies with other routers on the same network segment C. In the IS-IS broadcast network, routers with a priority of 0 also participate in the election of the DIS, while routers with a priority of 0 in OSPF do not participate in the election of the DR. See the full explanation below for the reasoning.
Question
Which of the following descriptions about the difference between DIS in IS-IS and DR in OSPF are correct? (Multiple choice)
Options
- AThe election of DIS and DR follow the principle of preemption
- BIn the IS-IS broadcast network, routers of the same level on the same network segment will form adjacency relationships, including all non-DIS routers will also form adjacencies with each other, and the DIS will also form adjacencies with other routers on the same network segment
- CIn the IS-IS broadcast network, routers with a priority of 0 also participate in the election of the DIS, while routers with a priority of 0 in OSPF do not participate in the election of the DR
- DThe election of DIS and DR is to compare the priority first, and then compare the MAC address
