Q230. The networking is as shown in the figure, RTA, RTB are located in AS 100, RTC, RTD, RTE are located in AS 200, AS 100 advertises BGP route 1.0.0.0/24 to AS 200, the main configuration of BGP of RTC and RTD is as follows, may I ask the BGP route on RTE 1.0.0.0/24 Who does the next hop point to?
RTC]
bgp 200
peerRTA as-number 90
peerRTD as-number 200
peerRTA preferred-value 100
peerRTA route-policsetlp import
route-policsetlp permit node 10
appllocal-preference 200
RTD]
bgp 200
peerRTB as-number 100
peerRTC as-number 200
peerRTA route-policsetlp import
route-policsetlp permit node 10
appllocal-preference 300
