Perform the following configurations on RTA , RTB and RTC respectively:
RTA]ospf 1
RTA-ospf-1]area 1
RTA-ospf-1-area-0.0.0.1]network 192.168.1.0 0.0.0.255

Which of the following statements is true ______

In the IS-IS network as shown in the figure, when the route is stable, shut down the interface where the IP address 192.168.24.1 is located on the RTB. Then IS-IS topology ______ , IP routing information ______ .

The three autonomous systems AS200 shown in the figure are the filtering ASs of AS100 and AS300, among which AS100 advertises the route 10.1.1.0/24 to AS200.
The main device configuration is as follows:
RTC
bgp 100
network 10.1.1.0 255.255.255.0
undo snchronization
peer 200.1.2.2 as-number 200
peer 200.1.2.2 route-policCOM export
peer 200.1.2.2 advertise-communit#
route-policCOM permit node 10
applcommunit100:100
#
RTB
#
bgp 200
undo snchronization
peer 200.1.2.1 as-number 100
peer 200.1.3.2 as-number 300
peer 200.1.2.1 route-policCOM import
#
route-policCOM permit node 10
if-match communit10
applcommunit200:200
#
ip communit-list 10 permit 100:100
Then on the RTC, the correct statement about the routing of 10.1.1.0/24 is ____.
