IPSG can defend against IP address spoofing attacks. Which of the following descriptions of IPSG are wrong? (Multiple choice)

A certain enterprise network is shown in the figure, in which CE and PE communicate with each other by deploying EBGP. At this time, CE1 transmits a private network route to PE1.

what are the errors in the following analysis of this scenario? (Multiple choice)

On the network shown in the figure, OSPF is deployed on R1 and R2. IS-IS is deployed on R2 and R3. To enable R1 to obtain the route to 10.0.3.3/32, ISIS routes are imported into OSPF on R2. In this case, the next hop address to 10.0.3.3/32 in the routing table of R1 is_____.

The LSP information generated by an IS-IS router itself is shown in the figure. From the LSP information, it can be inferred that the router is configured with 5 IPv6 addresses.

In the network shown in the figure, R1 and R2 have established an EBGP neighbor relationship through the Loopback0 interface. R1 introduces the route 2001::1/128 into BGP. In the Update message sent by R1, the value of the Next Hop field in MP_REACH_RI is 2000::1.

The AS-External-LSA generated by a router is shown in the figure. Based on this LSA, which of the following descriptions are correct? (Multiple choice)

As shown in the figure, when a network engineer is troubleshooting, he draws a schematic diagram of a multicast network. The IGIP version enabled by R1 and R2 is 2, PIM-SM is used as the multicast routing protocol, and other configurations are default configurations. The querier in the multicast network is ().

In a BGP/IPLS IP VPN network, the output information of a PE device VPN1 is shown in the figure. When the VPIv4 route corresponding to VPN1 is advertised to the remote PE, which VPNs of the remote PE will receive the route? (Multiple choice) ip vpn-instance VPN1 ipv4-family route-distinguisher 100:1 vpn-target 100:1 200:1 300:1 export-extcommunity

In the network shown in the figure, R1, R2, R4, and R5 run IS-IS in area 49.0001. R3 and R6 run IS-IS in area 49.0002. Configure "import-route isis level-2 into level-1" on R2 and R5. Inside AS65000, R1, R3, R4, and R6 establish IBGP neighbor relationships with R2 and R5, of which R2 and R5 are RRs and R1, R4, R3, and R6 are clients. IBGP neighbor relationships are all established using the Loopback0 interface. The IP address of the Loopback0 interface of each device is 10.0.X.X/32, and the Router ID is 10.0.X.X, where X is the device number. R1 and R4 import the external network 192.168.1.0/24 into BGP, and R3 and R6 import the external network
192.168.2.0/24 into BGP.

Which of the following descriptions are correct by default? (Multiple choice)

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.

Use the "display current-configuration |include 10.0.2.*" command on the router to see all the information including "10.0.2" in the current configuration.

In the OSPF network shown in the figure, the area numbers are marked in the figure, where area
1 is an NSSA area, and areas 2 and 3 are common areas. The "default-route- advertise always" command is configured in the SPF process of R5. Which of the following routers have default routes in their routing tables? (Multiple choice)

In a BGP/MPLS IP VPN network, VPNv4 routing transfer will carry RD values. Which of the following path attributes does MP-BGP use to carry the RD value?

An enterprise network is shown in the figure. If CE2 is dual-owned by PE2 and PE3, a Type 5 LSA routing loop may occur. The loop can be prevented by setting the route-tag command on PE2 and PE3 devices. When the Route Tag of the route received by PE3 is the same as the local configuration, the route will be ignored.

In the IS-IS network shown in the figure, the link cost value has been marked in the figure. R1 turns on IS-IS Auto FRR, then the main path for R1 to reach 10.0.3.3/32 is R1- R2-R3, and the backup path is R1-R4-R2-R3.
