Question 51
Which of the following description of the routing policy supported by OSPF route filtering is wrong?
Question 52
The routing tool route-policy can filter and set BGP attributes based on pre-defined conditions, so it is often used to define policies for BGP peers, and is often used during route generation. By default all unmatched routes are rejected to go through route-policy.
Question 53
In a company network environment, there are two switches SWA and SWB. The link aggregation LACP mode is adopted between the SWA and the SWB. There are three links added to the link aggregation, and the maximum number of active links is set to two. The system priority of the SWA is 4096. The system priority of the SWB is 32768. The interfaces of the three SWA links are G0/0/1, G0/0/2, and G0/0/3. The priority of the interface is 10, 20, 30. The interfaces of the three SWB links are G0/0/1, G0/0/2, and G0/0/3. The priority of the interface is 30, 20, and 10 respectively.
Which of the following conclusions are correct? (Multiple choice)
Question 54
PIM-DM does not rely on a specific unicast routing protocol but uses an existing unicast routing table for RFF checking.
Question 55
The ABRs in an OSPF stub area do not flood Type 5 LSAs, Type 4 LSAs, and Type 3 LSAs into the Stub area. Therefore, the Stub area does not have AS external routing capabilities. The ABR in the Stub area advertises a default route to the area to guide the data. How the package reaches the destination outside the AS.
