Question 31

In the network composed of the following three ASs, AS200 advertises the local network segment route 10.1.1.0/24 to the outside.
The main device configuration is shown below.
RTA :
bgp 100
dampening
undo snchronization
peer 1.1.1.1 as-number 200
peer 2.2.2.2 as-number 300
peer 1.1.1.1 ebgp-max-hop 2
peer 1.1.1.1 connect-interface LoopBack0
peer 2.2.2.2 ebgp-max-hop 2
peer 2.2.2.2 connect-interface LoopBack0
RTB :
bgp 200
network 10.1.1.0 255.255.255.0
undo snchronization
peer 10.10.10.10 as-number 100
peer 10.10.10.10 ebgp-max-hop 2
peer 10.10.10.10 connect-interface LoopBack0
The attenuation value of the system is 1000 each time, and the default parameters for attenuation are:
Ceiling Value: 16000
Reuse Value: 750
Reach HalfLife Time(in second): 900
Unreach HalfLife Time(in second): 900
Suppress-Limit: 2000
Then, after the local network segment 10.1.1.0/24 of RTB oscillates continuously for ____ times (and then resumes immediately after interruption), the route will no longer exist on the RTC until the penalty value of the route of RTB is less than ____.

Question 32

In H3C equipment, the default priority value of OSPF internal routing is ________.
