QUESTION 52
The link state value information between different ISIS processes of multiple routers is considered to be isolated.

QUESTION 53
When there are multiple redundant links in the IS-S network, multiple equal-cost routes may appear.
Regarding equal-cost routes in an IS-IS network, which of the following descriptions is wrong?

QUESTION 54
There are multiple types of MAC address entries on the switch. Which of the following types of entries can discard messages by matching the source MAC address of the received message, thereby achieving the purpose of filtering out illegal users.

QUESTION 58
Which of the following regular expressions can only match BGP routing entries that pass through AS200 and then AS300?

QUESTION 59
Based on the locally maintained LSDB, the device running the OSPF protocol calculates the shortest path tree with itself as the root through the SPF algorithm, and determines the next hop to the destination network based on this shortest path tree. If the network changes frequently, the maximum interval of the SPF calculation can be set to 0 to increase the speed of route convergence.

QUESTION 66
IS-IS is a link state routing protocol that uses the SPF algorithm for routing calculations. A park has deployed IPv4 and IPv6 at the same time and runs IS-IS to achieve network interconnection. As shown in the figure, the network IPv4 and IPv6 have the same overhead, and R1 and R4 only support IPv4. By default, in the calculated IPv6 shortest path tree, the next hop device for R2 to access R6 is () (Note: The device name must be consistent with the figure, such as: R1)
