Pretty cool questions,

BGP uses the Transport Control Protocol (TCP) with port number 179 as the transport layer protocol

Hi zaheernew,

BGP uses Transport Control Protocol (TCP) as the transport layer protocol, which enhances BGP reliability.
BGP selects inter-AS routes, which poses high requirements for stability. Therefore, using TCP enhances BGP's stability.
BGP peers must be logically connected through TCP. The destination port number is 179 and the local port number is a random value.
For more information, you can refer to https://support.huawei.com/hedex/hdx.do?docid=EDOC1100168821&id=EN-US_CONCEPT_0172354362&lang=en
I hope it helps!
