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 establishes a Level-1 adjacency relationship with RTA, RTC. After the routing of each router is stable, when RTB accesses 192.168.14.1, it chooses the next hop as _________.
If RTA and RTC are added the following configuration at this time:
RTA-isis-1]import-route isis level-2 into level-1
RTC-isis-1]import-route isis level-2 into level-1
Then RTB selects the next hop as ________ when accessing 192.168.14.1.
As shown in the figure, RTB establishes EBGP neighbor relationship with RTA and RTD, and AS100 uses confederation to solve large-scale routing problems. If RTA advertises route 10.1.1.0/24 to RTB.
Then regarding the advertisement of the route on RTB, the following statement is correct is ______.
b In the OSPF protocol, the destination address used by the router to send the update message to the DR router is _____.
In the topology shown in the figure, the following configurations are performed on the RTA and RTC respectively:
RTA-ospf-1] area 1
RTA-ospf-1-area-0.0.0.1] authentication-mode simple
RTA] interface GigabitEthernet0/0
RTA-GigabitEthernet0/0] ospf authentication-mode simple plain 12345
RTC-ospf-1] area 0
RTC-ospf-1-area-0.0.0.0] authentication-mode simple
RTC] interface GigabitEthernet0/0
RTC-GigabitEthernet0/0] ospf authentication-mode simple plain 54321
If RTB needs to establish neighbor relationship with RTA and RTC respectively, which of the following configuration needs to be performed on RTB?
In OSPF, the types of LSAs that cannot be aggregated by ASBR are _______
