19. What are the main steps included in the IS-IS protocol routing calculation? (Multiple Choice)


20. If the router-id is configured in the system view and the BGP view of router, becuase of the high priority of the BGP view, the BGP view uses the router-id in the BGP view.


21. Which of the following description of OSPF is correct?


22. Which of the following BGP attributes are not included in the Update message of the BGP route? (Multiple Choice)


23. Both policy routing and routing policies can affect the forwarding process of data packets, but they affect the packets differently. Policy routing is based on policy-based forwarding. Find the routing table forwarding after failure. Based on the forwarding plane, it serves the forwarding policy and needs to be manually configured. The routing policy is based on the destination address and is forwarded according to the routing table. Based on the control plane, it serves the routing protocol and the routing table, and combines with the routing protocol to complete the policy.
