사용 지침

 명령을 사용하여 네이버 세션에 대한 BGP 및 TCP 연결을 표시할 수 있습니다. 

BGP의 경우 자세한 네이버 특성, 기능, 경로 및 접두사 정보가 포함됩니다. TCP의 경우 BGP 네이버 
세션 설정 및 유지 관리와 관련된 통계가 포함됩니다.

접두사 활동은 보급 및 취소된 접두사 수를 기반으로 표시됩니다. 정책 거부는 보급되었지만 출력
에 표시된 기능 또는 특성에 따라 무시된 경로 수를 표시합니다.

4바이트 자동 시스템 번호의 Cisco 구현에서는 asplain(예: 65538)을 자동 시스템 번호의 기본 정규
식 일치 및 출력 표시 형식으로 사용하지만 RFC 5396에 설명된 대로 asplain 형식과 asdot 형식으로 
4바이트 자동 시스템 번호를 구성할 수 있습니다. 4바이트 자동 시스템 번호의 기본 정규식 일치 
및 출력 표시를 asdot 형식으로 변경하려면 clear bgp * 명령이 뒤에 오는 bgp asnotation dot 명령
을 사용하여 모든 현재 BGP 세션의 하드 재설정을 수행합니다.

예

예제 출력은 show bgp neighbors 명령에 사용할 수 있는 여러 키워드에 따라 다릅니다. 여러 키워
드를 사용한 예제는 다음 섹션에 나와 있습니다.

예

다음 예에서는 10.108.50.2에 있는 BGP 네이버에 대한 출력을 보여 줍니다. 이 네이버는 iBGP(내
부 BGP) 피어입니다. 이 네이버는 경로 새로 고침 및 정상 재시작 기능을 지원합니다.
