Is the black hole statement correct? (multiple choice)
In BGP/MPLS IP VPN, the 0SPF multi-instance process uses the DN bit to prevent Type5 LSA loops.
Which of the following statements is false when troubleshooting the dual-active failure of a VRRP backup group?
Ethernet is a broadcast-enabled network, and once there are loops in the network, this simple factory broadcast mechanism can have disastrous consequences. Which of the following phenomena may be caused by loops?

A campus deploys both IPv4 and IPv6 networks for service testing, and runs IS-IS to realize network interconnection. The IS-IS routing protocol has good scalability and is widely used in the existing network. Which of the following statements is true about IS-IS scalability?
As shown in the figure, private network routing information is exchanged between PE1 and PE2 and their respective CEs through OSPF, and the same DomainlD is set on both PE1 and PE2. When routes are imported from BGP to OSPF on PE2, it is possible that Which of the following types of SAs are passed to CE2?
Which of the following statements about the MP_REA, CH_NLRI attribute of BGP4+ is correct?
When 0SPFV2 evolves to 0SPFV3, the LSA format and function are exactly the same, but the network layer in the LSA address from IPv4 to IPv6o
Which of the following are documents that need to be handed over as part of the wrap-up of a structured network troubleshooting process
files?

IEIF expands the functions of OSPF by taking advantage of the strong expansibility of OSPF. To enable it to support IPv6 networks, the expanded protocol is called OSPFv3. OSPFv3 is compatible with OSPFv2.
The ipv6 enable topology standard has been set in the S-IS protocol view. The meaning of this command is:
Pv4 shares a topology with IPv6.
As shown in the figure, on the R1 router, the network administrator can control the path of the traffic entering AS100 after modifying the value of the routing entry sent to R2 through the routing policy.
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
Network administrator A wants to use the AS-Path Fiter to match the routing entries of the BGP routing attribute AS_PATH [100 200 300]. Network administrator A sorts out the four configurations in the figure. Which of the following configurations can satisfy network administrator A's requirements? Require?
OSPF is deployed in a campus to achieve network interworking, and OSPF is also enabled on the GEO/0/2 interface of R3. Area1 is deployed as an NSSA area, and the device addresses are shown in the figure. An engineer configures a static route on R3 to access the loopback interface address of R4, and imports the static route in the 0SPF process. At this point, in the Type5 LSA received by R1, the forwarding address (FA) is____. (Note: Please fill in the IP address without mask)
The rules of RR advertising routes violate the rules of IBGP split horizon, so it may cause loops in the AS
road. Which routing attributes does RR use to prevent loops?
Qing technology is a technology to expand VLAN space. It can achieve the function of expanding Vian space by adding a layer of 8D2.1Q Tag on the basis of 8Q2.12 tag message. Which of the following statements about qinq is false?
Configure ipv6 preference in IS-IS protocol view. The function of this command is to configure the priority of IPv6 routes generated by IS-Is protocol.
When configuring the DHCP Relay function on the device, the VLAN ANIF interface of the relay connection client must be bound with a DHCP server group, and the IP address of the proxy DHCP server must be configured in the bound DHCP server group.

Be consistent and can be modified under the process through the domain-id command
In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.
Label, a description of the two-layer label in the following options. What is wrong is:
The router ID of OSPF V3 needs to be configured in dotted decimal with a length of 128 bits.
