설명

BGP neighbor 

BGP 네이버의 IP 주소 및 자동 시스템 번호입니다. 네이버가 라우터와 동일한 
자동 시스템에 있는 경우 둘 사이의 링크는 내부 링크입니다. 그렇지 않으면 
외부로 간주됩니다. 

remote AS 

네이버의 자동 시스템 번호입니다.

internal link 

이 피어가 iBGP(내부 Border Gateway Protocol) 피어임을 나타냅니다. 

BGP version 

원격 라우터와 통신하는 데 사용되는 BGP 버전입니다. 네이버의 라우터 ID(IP 
주소)도 지정됩니다. 

remote router ID 

마침표로 구분된 4개의 옥텟으로 작성되는 32비트 숫자입니다(점으로 구분된
