On the ISIS network shown in the figure, R1 imports a default route using the default-route-advertise always level-1 command. In this case, R3 can learn this default route through IS-IS.
On the OSPFv3 network shown in the figure, OSPFv3 is enabled on the interfaces connecting R1, R2, and R3. The router ID of each router is 10.0.X.X, where X is the number of the router. If you check detailed information about an LSA on R3, the command output shows that the LSA is generated by R2 and describes the IPv6 prefix address associated with the Router-LSA.
On the OSPF network shown in the figure, the cost values of links are marked, and OSPF IP FRR is enabled on R1. Which of the following statements is false?
For high reliability purposes, the following LDP messages are transmitted through TCP: discovery messages, session messages, advertisement messages, and notification messages.
The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2____, ____, ____, ____.
100 This space corresponds to the [A] space in the routing policy
200 This space corresponds to the [B] space in the routing policy
300 This space corresponds to the [C] space in the routing policy
400 This space corresponds to the [D] space in the routing policy
