예: IS-IS 프로토콜에 대한 백업 선택 정책 구성
이 예는 IS-IS 프로토콜에 대한 백업 선택 정책을 구성하는 방법을 보여줍니다.
백업 선택 정책을 활성화하면 Junos OS에서 정책 규칙과 네트워크에 있는 링크 및 노드의 속성을 기반으로 LFA를 선택할 수 있습니다. 이러한 속성은 admin-group, srlg, bandwidth, protection-type, metric, neighbor, neighbor-tag입니다.
요구 사항
이 예에서 사용되는 하드웨어 및 소프트웨어 구성 요소는 다음과 같습니다.
에지 라우터와 코어 라우터의 조합이 될 수 있는 라우터 8개.
모든 디바이스에서 실행되는 Junos OS.
시작하기 전에:
디바이스 인터페이스를 구성합니다.
IS-IS를 구성합니다.
개요
기본 LFA(loop free alternative) 선택 알고리즘 또는 기준은 LFA 정책으로 재정의할 수 있습니다. 이러한 정책은 각 대상(IPv4 및 IPv6) 및 기본 다음 홉 인터페이스에 대해 구성됩니다. 이러한 백업 정책은 백업 경로의 admin-group, srlg, bandwidth, protection-type, metric, neighbor 및 neighbor-tag 속성을 기반으로 LFA 선택을 시행합니다. 백업 최단 경로 우선(SPF) 계산 중에 백업 다음 홉당 저장된 백업 경로의 각 속성(노드 및 링크 모두)이 IGP에 의해 누적됩니다. IGP에 의해 내부적으로 생성된 경로의 경우, 모든 백업 경로의 속성 세트는 각 목적지(IPv4 및 IPv6) 및 기본 다음 홉 인터페이스에 대해 구성된 정책에 대해 평가됩니다. 첫 번째 또는 최상의 백업 경로가 선택되어 라우팅 테이블에서 백업 다음 홉으로 설치됩니다. 백업 선택 정책을 구성하려면 계층 수준에서 구성 문을 포함 backup-selection 합니다. [edit routing-options] 이 명령은 show backup-selection 지정된 인터페이스 및 대상에 대해 구성된 정책을 표시합니다. 디스플레이는 특정 대상, 접두사, 인터페이스 또는 논리적 시스템에 대해 필터링될 수 있습니다.
위상수학
이 토폴로지에서 백업 선택 정책은 디바이스 R3에서 구성됩니다.

구성
CLI 빠른 구성
이 예를 빠르게 구성하려면, 아래 명령을 복사하여 텍스트 파일로 붙여 넣은 다음 모든 라인브레이크를 제거하고, 네트워크 구성을 일치하는 데 필요한 세부 사항을 변경한 다음, 계층 수준에서 [edit] 명령을 복사하여 CLI에 붙여 넣습니다.
