Huawei Certified Network Professional - Routing Switching Fast Track Exam - Question 23


Which types of packets are supported by BGP? (Choose three.)

Show Answer
Correct Answer: BCD

BGP (Border Gateway Protocol) supports Notification, Update, and Route-refresh packets. Notification packets are used to signal errors and the closure of connections. Update packets are used to advertise new routes or withdraw previously advertised routes. Route-refresh packets allow a BGP speaker to request the re-advertisement of the entire routing table from a neighbor. Hello packets are not used in BGP; they are used in other protocols like OSPF.
