In the three autonomous systems shown in the figure, AS200 is the filtering AS of AS100 and AS300, and AS100 internally generates routes
10.1.1.0/24 , 10.1.2.0/24 , 10.1.3.0/24 .
The main device configuration is shown below.
RTC:

network 10.1.1.0 255.255.255.0
network 10.1.2.0 255.255.255.0
network 10.1.3.0 255.255.255.0
undo snchronization
peer 200.1.2.2 as-number 200
RTB :
bgp 200
