(Drag and drop question) The configuration shown in the figure is performed on R2 to filter all incoming routes. Suppose there is an entry on R1 AS_Path attribute is [100 200 300 400] BGP routes need to be sent to R2, please help network administrators in Adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be routed by R2 route^policy AS-PATH permit node 10 if-match as-path-filter BGP route-policy AS-PATH deny node 20 ip as-path-filter BGP permit A[A2]00 400 100_

정답: C
After the VLAN-based MA, C address flapping detection function is configured, if the MA, C address flaps. The interface can be configured to perform actions according to requirements. Which of the following is NOT a configurable action?
정답: C
When B, CPIMPLS TP VPN is deployeD. the OSPF VPN Route Tag (VPN Route Tag) is not transmitted in the extended community attribute of MP-BGP, but the local concept is only meaningful on PE routers that receive MP-BGP routes and generate OSPF LSAs.
정답: B
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.

정답: A
An engineer uses two routers to test IPv6 services, and runs 0SPFv3 to implement IPv6 network interconnection.
R1 is required to be able to access the loopback interface address of R2.
The engineer checked the OSPFv3 routing table entry of R1, as shown in the figure, and found that there was no route to the loopback interface address of R2. Which of the following reasons could not be the cause?
