Q442. When a router running BGP receives a route with an unreachable next hop, how to deal with it?

Refuse to join the BGP routing table, and silently discard

Receive the route, add it to the BGP routing table, participate in the BGP routing rules, it may be selected as the best route, and add it to the IP routing table

Receive the route and add it to the BCP routing table. But this route will not be selected by BCP and will not be added to the IP routing table

Q445. Which of the following descriptions about VRRP fast switching is wrong? (Multiple choice)

If multiple BFDs are configured to monitor at the same time, each configuration is related to each other and may affect each other

The VRRP backup group monitors common BFD and when the BFD state changes, it will change the master/standby state by modifying the priority of the backup group. When the monitored BFD session state recovers, the priority of the router in the backup group will be restored to original value

A VRRP backup group cannot monitor Peer BFD, Link BFD and Normal BFD at the same time

Use VRRP to monitor the BFD session or EFM function. After the BFD session or EFM session status changes, the VRRP module will be notified to realize VRRP fast switching

(Multiple choice)
<R1>display ospf interface Gigabitethernet 0/0/0

Interface: 10.0. 12.1(Gigabitethernet 0/0/0)
Cost: 1 State: DR Type: Broadcast MTU: 1500
Priority: 1
Designated Router: 10.0. 12.1
Backup Designated Router: 10.0.12.2
Timers: Hello 10,Dead 40,Poll 120,Retransmit 5,Transmit Delay 1

This router is the DR

The interface address of this router is 10.1.12.1

The Router-ID of this router is 10.1.1.1

The network type of this interface is broadcast

Q455. Which of the following description of VRRP is wrong?

VRRP determines the status of each router in the virtual router based on priority

If the Master already exists, Backup will also preempt.

When two routers with the same priority compete for the Master at the same time, compare the size of the interface IP address, and the one with the larger interface address is elected as the Master

If the Backup router works in non-preemptive mode, as long as the Master router does not fail, the Backup router will not become the Master router even if it is subsequently configured with a higher priority.
