What is the main difference between 1.bgp-4 and earlier versions?

2. What are the two issues that CIDR solves?

3. What is the difference between a category and an classless IP router?

4. What is the difference between a category and an classless IP routing protocol?

5. Please explain how the rollup hides the instability of the network.

6. Explain how the rollup produces an asymmetric traffic model.

7. Asymmetric flow is not expected?

8. What is NAP?

9. What is a routing server

10. What is a separate address space with the provider? What are the benefits of having this address?

11. Why there is a problem with a provider-independent/21 address.

12. What is a routing policy

What is the underlying protocol BGP uses to reliably connect its neighbors?

The 4 message types of BGP are those that have no message type advantage to use.

15. In what state, the BGP peer self-build can exchange the update message.

16. What is NLRI

17. What are path properties

What are the 4 path attributes of BGP?

What is the role of the As_path property

What different types of attributes are included in Ap_path

What is the role of the Next_hop attribute?

What is the role of the Local_pref property

What is the effect of the Multi_exit_disc attribute?

The BGP speaker initiates an aggregated route which is useful for what or those attributes

25. What is the administrative weight of BGP

26. Assume that there are two routes to the same destination, one is EBGP and the other is IBGP, which route will be preferred by BGP

27. The router has two routes to the same destination, the local_pref of path A is 300, and there are 3 as numbers in As_path, the local_pref of Path B is 200, and 2 as in As_path, assuming the other is exactly the same, Which path does the router choose?

28, what is Route damping

29, please give a way out of the definition of the penalty in damping, suppression threshold, reuse threshold and half-life

What is IGP synchronization and why synchronization is important.

Under what circumstances can the IGP synchronization mechanism be closed safely.

What is a BGP peer group

What is BGP community

What is a route reflector? What is the route reflection client and what is the route reflection family

What is the role of the path attribute origiator_id and cluster_list?

What is BGP Federation

Can the route reflector function within the Federation

What is the function of next-hop-self? Are there other alternatives to implementing this feature?
