The correct answer is B. If there are multiple RRs in an AS, the Originator_ID attribute is created by the first RR C. When a route is reflected by RR for the first time, RR adds the Originator_ID attribute to this route to identify the originating router of this route. See the full explanation below for the reasoning.
Question
Which of the following descriptions about the Originator_ID attribute in BGP is correct? (Multiple choice)
A. Originator_ID is a recognized arbitrary attribute.
B. If there are multiple RRs in an AS, the Originator_ID attribute is created by the first RR
C. When a route is reflected by RR for the first time, RR adds the Originator_ID attribute to this route to identify the originating router of this route.
D. If the Originator_ID attribute already exists, RRs will compare the received Originator_ID with the local RouterID. If the two IDs are the same, BGPSpeaker will ignore this route and do not process it.
