R2 sends the LSP to R3 and R4 in unicast mode

If R1 sends an LSP message, R2 needs to send PSNP for confirmation

Source IP

Source MAC

Destination IP

Destination port

QUESTION 96
Regarding the description of the characteristics of the routing strategy, which is correct?

Application command policy- based-route

Forwarding according to the routing table based on the destination address

Manual hop-by-hop configuration is required to ensure that packets are forwarded according to the policy

QUESTION 97
Which of the following statements about the BFD detection mode is correct? (Multiple choice)

Asynchronous mode is a commonly used BFD detection mode

In query mode, once the BFD session is established, the system will no longer send BFD control packets periodically

Asynchronous detection mode does not support echo function

In asynchronous mode, the systems will send BFD control packets according to the negotiated period.
If a system does not receive the BFD control packet from the peer within the detection time, it will declare the status of the BFD session as Down.

How does an IGMPv2 router maintain network segment group membership? (Multiple choice)

The router maintains a timeout timer for each group membership. If the receiver host is received, the timer is refreshed. If the timer expires, the group membership is deleted.

After receiving the eave message, the router immediately deletes the group membership

The router periodically sends a Query message, and the receiver host reports a Report message after receiving the Query message

The router will query for a specific group

QUESTION 101
Which of the following descriptions about configuring the dual-machine hot backup function in the WLAN network is wrong?

When dual-link hot backup is switched over, due to the long switching time, the business data forwarded by the tunnel will be interrupted during this period, and new users will not be able to go online, and the online users will not be able to roam.
