An MSR router has four interfaces whose IP addresses are Loopback0:1.1.1.1/32, Loopback1:2.2.2.2/32, GE0/0:172.16.1.1/30, and GE0/1:192.168.1.1/30. Running OSPF protocol and enabling OSPF on only two interfaces, the Router ID selected by this router is _______.

Execute displaip policy-based-route statistic interface ethernet1/0 on the router, there is the following output
Interface Ethernet1/0 policbased routing statistics information :
policy-based-route : aaa
permit node 5
apploutput-interface serial1/0
Denied : 0 ,
Forwarded : 0
Total denied : 0 ,
forwarded : 0
According to the above output. Know __________

In the IS-IS network shown in the figure, RTB is configured with route aggregation.
So which of the following routes are included in the IS-IS routing table of RTC?

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
peer 200.1.3.2 advertise-communit#
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 ____.

In the topology shown in the figure, the following configurations are performed on RTA, RTB, RTC and RTD respectively:
