Although adjacency will be formed between routers of the same level on the same network segment of IS-IS in the broadcast network, that is, adjacency will be formed between all non- DIS routers, in the implementation of IS-IS and BFD linkage, BFD sessions are only established between DIS and non-DIS, and BFD sessions are not started between non-DIS.
- A . True
- B . False
In order to publish the external routes introduced by the NSSA area to other areas, the Type 7 LSA needs to be converted into a Type 5 LSA so that it can be announced in the entire OSPF network. By default, the router that performs LSA conversion is the area border router (ABR) with the largest router ID in the NSSA area.
- A . True
- B . False
As shown in the figure, in order to realize the correct transmission of VPN routes in the Hub&Spoke network, the administrator deployed IGP between Hub-PE and Hub-CE, and deployed EBGP between Spoke-PE and Spoke-CE.
- A . True
- B . False
The LSP fast diffusion feature can speed up the diffusion of LSP. Under normal circumstances, when IS-IS receives an LSP from another router, if this LSP is newer than the corresponding LSP in the local LSDB, it updates the LSP in the LSDB and uses a timer to periodically diffuse the updated LSP in the LSDB. When a device with the LSP fast diffusion feature enabled receives one or more newer LSPs, it diffuses LSPs less than the specified number before route calculation to speed up the synchronization process of the LSDB.
- A . True
- B . False
The Router ID of R4 is 10.0.4.4. In the LSDB of R4, the LSA shown in the figure is seen. The network engineer makes the following inferences based on the LSA. Which one is wrong?
- A . This LSA is generated by R4
- B . R4 has two OSPFv3 neighbors
- C . R4 is the DR on both links
- D . R4 does not support importing external routes into OSPFv3
For the OSPF network shown in the figure, please drag the values on the left to the correct position so that the traffic from PC1 to PC2 is PC1-R1-R3-R2-PC2: the traffic from PC2 to PC1 is PC2-R2-R1-PC1.
In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The Router ID of each device is 10.0.XX, and the AS number is 6500X, where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are introduced into BGP through import.
If the "ageregate 192.168.1.016 detail-suppresed command" is configured on R1, which of the following is the traffic path from R3 to 192.168.1.0/24?
- A . R3-R2-R1
- B . R3-R5-R1
- C . RЗ-R6-R5-R1
- D . R3-R5-R4
The Link-LSA generated by an OSPFv3 router is shown in the figure. Which of the following is the number of global unicast addresses configured on the interface?
- A . 4
- B . 3
- C . 1
- D . 2
MPLS supports multi-layer label nesting. When the device receives an MPLS message, it will first process the label close to the second-layer header, that is, the MPLS label at the top of the stack.
- A . True
- B . False
The business route of an enterprise is transmitted in the network, and part of the configuration of PE1 and PE2 is shown in the figure. At this time, CE1 adds a new business network segment and announces it to Area1 of OSPF 10.
In this scenario, which type of LSA will CE2 receive, which will contain the service network segment newly announced by CE1?
- A . True
- B . False
