예: OSPF 또는 OSPF3 프로토콜에 대한 백업 선택 정책 구성
이 예에서는 네트워크에서 LFA(loop-free alternate)를 선택할 수 있는 OSPF 또는 OSPF3 프로토콜에 대한 백업 선택 정책을 구성하는 방법을 보여줍니다.
백업 선택 정책을 활성화하면 Junos OS는 네트워크의 링크 및 노드의 정책 규칙 및 속성에 따라 LFA를 선택할 수 있습니다. 이러한 속성은 admin-group, srlg, bandwidth, protection-type, metric, node입니다.
요구 사항
이 예에서 사용되는 하드웨어 및 소프트웨어 구성 요소는 다음과 같습니다.
M 시리즈 멀티서비스 에지 라우터, MX 시리즈 5G 유니버설 라우팅 플랫폼, PTX 시리즈 패킷 전송 라우터, T 시리즈 코어 라우터로 조합할 수 있는 라우터 8개
모든 디바이스에서 Junos OS 릴리스 15.1 이상 실행
시작하기 전에:
디바이스 인터페이스를 구성합니다.
OSPF를 구성합니다.
개요
Junos OS에서는 기본 LFA(loop-free alternative) 선택 알고리즘 또는 기준을 LFA 정책으로 재정의할 수 있습니다. 이러한 정책은 각 대상(IPv4 및 IPv6)과 기본 다음 홉 인터페이스에 대해 구성됩니다. 이러한 백업 정책은 백업 경로의 admin-group, srlg, 대역폭, protection-type, metric, node 속성에 따라 LFA를 선택합니다. 백업 최단 경로 우선(SPF) 계산 중에 백업 다음 홉마다 저장된 백업 경로의 각 속성(노드 및 링크 모두)이 IGP에 의해 누적됩니다. IGP에 의해 내부적으로 생성된 경로의 경우, 모든 백업 경로의 속성 집합은 각 대상(IPv4 및 IPv6) 및 기본 다음 홉 인터페이스에 대해 구성된 정책에 대해 평가됩니다. 첫 번째 또는 최적의 백업 경로가 선택되어 라우팅 테이블의 백업 다음 홉으로 설치됩니다. 백업 선택 정책을 구성하려면 계층 수준에서 구성 문을 [edit routing-options] 포함합니다backup-selection. 명령은 show backup-selection 지정된 인터페이스 및 대상에 대해 구성된 정책을 표시합니다. 디스플레이는 특정 대상, 접두사, 인터페이스 또는 논리적 시스템에 대해 필터링할 수 있습니다.
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 바꾸고 [edit] 계층 수준에서 명령을 CLI로 복사해 붙여 넣은 다음, 구성 모드에서 commit을(를) 입력합니다.
