Start to test:

1. As shown, RTA, RTB and RTC run BGP routing protocol, analysis configuration.

RTA:

bgp 100

peer 13.13.13.2 as-number 200

ipv4-family unicast

network 12.12.12.0 255.255.255.252

undo synchronization

peer 13.13.13.2 enable

RTB:

bgp 100

peer 23.23.23.2 as-number 200

ipv4-family unicast

network 12.12.12.0 255.255.255.252

undo synchronization

peer 23.23.23.2 enable

RTC:

bgp 200

peer 13.13.13.1 as-number 100

peer 23.23.23.1 as-number 100

ipv4-family unicast

undo synchronization

peer 13.13.13.1 enable

peer 23.23.23.1 enable

Debugging found that the neighbor relationship can be established normally, and the RTC's BGP routing table correctly received the RTA and RTB advertised routes 12.12.12.0/30.

For RTC, Which statement is correct?

A. By RTA access 12.12.12.0/30, because the bandwidth between RTA and RTC is greater than the bandwidth between RTB and RTC.

B. By RTA access 12.12.12.0/30, because RTA's router ID is smaller than the RTB's.

C. by RTB access 12.12.12.0/30, because the RTB router ID is greater than the RTA's.

D. In this case, RTC performs load balancing, simultaneous access 12.12.12.0/30 by RTA and RTB.
