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.
- A . True
- B . False

- A . The router ID of the router is 10.0.3.3
- B . The cost value of other routers to reach 2000::3 is always 1
- C . This LSA is generated by converting NSSA LSA
- D . The Route Tag value carried by this LSA is 1

To prevent attackers from forging BGP messages to attack devices, you can protect devices by configuring the CTSM function to detect the range of TTL values in the IP message header. If a device is configured with "peer xxxx valid-ttl-hops 100", the valid range of TTL values of the detected messages is [(), 255].
In the OSPF network shown in the figure, the network engineer found that the Router ID configuration of R1 and R2 is the same, and both R1 and R2 have introduced the default route (default-route-advertise always).
Which of the following descriptions of this scenario is wrong?
- A . R1 and R2 can establish a neighbor relationship
- B . R2 and R4 can establish a neighbor relationship
- C . A routing loop may occur between R3 and R4
- D . R1 and R3 can establish a neighbor relationship
When the switch is configured with the port isolation function, by default, different hosts belonging to the same VLAN cannot communicate at Layer 2 and Layer 3.
- A . True
- B . False
An enterprise network is shown in the figure. If CE2 is dual-owned by PE2 and PE3, a Type 3 LSA routing loop may occur. The loop can be prevented by setting the dn-bit-set disable command on PE2 and PE3 devices.
- A . True
- B . False
When an OSPF network fails, the following processes are required to switch traffic paths. Please sort the following processes according to the steps for fault recovery:
