Which of the following will not cause the VRRP backup group to flap?
The ORF function of BGP can control the routing entries sent by neighbors. In order to achieve this purpose, the BGP router will send the list of routes to be filtered to the neighbors. Which tool is generally used to send the list to the neighbors?
Which of the following operations is not part of the middle stage of dissection?
As shown in the figure, R1, R2, R3, and R4 are in the same PLs domain, and LDP is used to distribute IPLS labels between devices. R4 is the Egress LSR of the FEC 4.4.4.0/24. If you want to achieve R1 access
4.4.4.0/24, R4 does not need to query the label table but can know the forwarding priority of the data, then the outgoing label of R3 for the FEC should be:____. (Please fill in the Arabic numerals directly, without symbols)
As shown in the figure, in a medium-sized network, BGP generally deploys dual RRs to improve R reliability. When deploying dual RRs, the ClusterIDs of the two RRs are generally set to be the same. What is the reason for this?
In OSPF, the A, BR will convert all type 7 L SAs in the NSSA area to type 5 L SAs.
What is the meaning of ipv6 enable topology ipv6 in IS-IS protocol view?
The IS-IS neighbor relationship between R3 and R1 is not established. According to the information in this figure, what is the possible reason?
According to the configuration shown in the figure below, you can know that R4 has an interface advertised into IS-IS?
All routers in a network run IS-IS, and all are in Area 49.0001, where the L SDB of R1 is shown in the figure
According to this, it is judged that the DIS of Level-2 is. (Please fill in the device name, such as R1)

In an MPLS domain, LSR can be divided into Ingress LSR, Transit LSR and Egress LSR according to the different processing methods of LSRs for data. For the same FEC. a certain LSR can be the Ingress LSR of the FEC or the Transit LSR of the FEC. LSRO
A campus has deployed IPv6 for service testing. In the early stage of deployment, engineers wanted to achieve network interoperability through IPv6 static routes. When creating an IPv6 static route. You can specify both the outbound interface and the next hop, or only the outbound interface or only the next hop.
multiple equal-cost routes may appear. About the IS-IS network , which of the following descriptions is false?
