Deployment in a small and medium-sized networkOSPF,When viewing the routing table of a device, it is found that there are only directly connected routes.
It is not possible for the operation to cause the fault?
As shown in the figure, configure a backhaul summary route 10.0.0.0/24 on the border route RT1. next hop
to RT2. At the same time, the default route to the external network is configured. At this point, a routing black hole will appear. The following is about routing

If the temperature of the device is found to be too high, it can be concluded that the fan has failed
After the cutover is completeD. it is generally necessary to check the following items?
In OSPF, the A, BR will convert all type 7 L SAs in the NSSA area to type 5 L SAs.
CutoverThe previous information collection can be used to determine whether the services before and after the cutover are normal.
Since BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors.
The routing policy deployed between IBGP neighbors is invalid.
Which of the following reasons may cause the hosts in the same--VLAN LAN to fail to communicate with each other
A campus has deployed IPv6 for service testing. There are 4 routers in the network, running 0SPFv3 to implement IPv6 network interconnection. As shown in the figure, an engineer checked the LSDB of R2 and intercepted one of the Link-LSAs. Which of the following statements is true about the description of this LSA?
The partial configuration of R1 is as follows. Which statement about OSPF on R1 is correct?
ospf 1 router-id 172.16.1 J
area 0.0.0.0

In the VLAN aggregation technology, multiple Sub-VLANs are used to isolate wide-open domains, and these Sub-VLANs are aggregated.
Synthesizing a logical Super-VLAN, a company divides different departments into different Sub-VLANs, because
Sub-VL AN not only includes physical connection, but also can establish three-layer VLAN ANIF interface, which can directly carry out three-layer communication with external network.
What fields are added in Update in order to advertise IPv6 routes in BGP4+.
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, Client1 and Client2 act as clients of RR1 and RR2 at the same time, and RR1 and RR2 are in the same
In a Cluster, R introduces 10 routes. It is assumed that the configuration of B, CP is correct. Neighbor relations have been established 
Now, how many routing entries exist in the BGP routing table of Client2?
As shown below:
IR2] ad 2000
[R2-ad-basic-2000]rule deny
[R2-ad-basic-2000]quit

[R2-ospf-1-area-0.0.0,1] quit
[R2-ospf-1] default-route-advertise always
As shown in the figure, OSPF is enabled on all interfaces of the router, and the ip address identified in the figure is the device's IP address.
Loopback0 presses the IP address of the port, RI, R2, R3EJLoopbacD is advertised in the area 1, R4
LoopbacfkD advertises in area D and which of the following functional addresses can be pinged between the LoopbackD announcements of R5 and R5 in area 2?

The RR rules for advertising routes violate the IBGP split horizon rules, which may cause loops in the AS. Which routing attributes does RR use to prevent loops?
Which of the following operations is not part of the middle stage of dissection?
As shown in the figure, the MP_BGP neighbor relationship is established between PE1 and PE2 through the LoopbackO interface. After the configuration is complete, it is found that CE1 and CE2 cannot learn routes from each other. Which of the following options will cause this problem.
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
