예: 동일한 라우터 내의 논리적 시스템에서 IS-IS 구성
이 예는 단일 물리적 라우터에서 실행되는 여러 논리적 시스템을 사용하여 IS-IS 네트워크를 구성하는 방법을 보여줍니다. 논리적 시스템은 논리적 터널 인터페이스에 의해 연결됩니다.
요구 사항
논리적 터널(lt) 인터페이스를 사용하여 논리적 시스템을 연결해야 합니다. 예: MX 시리즈 라우터 및 EX 시리즈 스위치에서 논리적 터널 인터페이스를 사용하여 동일한 디바이스 내에서 논리적 시스템 연결을 참조하십시오.
개요
이 예는 하나의 물리적 라우터에서 실행되는 세 개의 논리적 시스템이 있는 IS-IS 구성을 보여줍니다. 각 논리적 시스템에는 자체 라우팅 테이블이 있습니다. 이 구성은 IS-IS 도메인에 참여하는 모든 논리적 터널 인터페이스에서 프로토콜을 활성화합니다.
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 계층 수준에서 명령을 CLI [edit] 로 복사해 붙여 넣은 다음, 구성 모드에서 commit을 입력합니다.
