Question 7
In the topology shown in the figure, perform the following configuration in RTA and RTB respectively:
RTA-ospf-1-area-0.0.0.1]network 192.168.0.0 0.0.0.255

Question 8
L is a network design engineer. In a certain network project, in order to reduce the complexity, the small L design network adopts a two-layer architecture, and the access layer functions are incorporated into the convergence layer. In the design, the small L takes into account that the core layer needs to have a fast convergence function, and the convergence layer performs route aggregation to reduce the number of routes. Among the following routing protocols, which should be used by L as the aggregation layer routing protocol? (Choose two)
Question 9
In the IS-IS network as shown in the figure, RTA, RTC, RTD, and RTE establish a Level-2 adjacency relationship with each other; RTB, RTA, and RTC establish a Level-1 adjacency relationship. After the reason of each router is stable, when RTB accesses 192.168.5.1, it chooses the next hop as ______.
If RTA adds the following configuration at this time:
RTA-isis-1]import-route isis level-2 into level-1
Then when RTB accesses 192.168.5.1 again, choose the next hop as ______.
Question 10
In the network shown in the figure, the BGP routing learning between the routers is normal, and the BGP routing attributes all take default values.
After the route 8.0.0.0 is imported into BGP on RTA, if the next hop of route 8.0.0.0 on RTD is to point to RTB, the following adjustment methods are feasible again.
