예: 네트워크 속도를 높이기 위해 IS-IS를 위해 SPRING에서 Anycast 및 Prefix Segment 구성
이 예는 네트워킹(SPRING) 또는 세그먼트 라우팅(SR)의 소스 패킷 라우팅에서 접두사 세그먼트, 세그먼트 라우팅 글로벌 블록(SRGB), Adjacency Segment Hold Time 및 명시적 null flag를 구성하는 방법을 보여줍니다. 이 구성은 네트워크 속도를 증가시켜 네트워크를 단순화하는 데 도움이 됩니다.
요구 사항
이 예는 다음과 같은 하드웨어 및 소프트웨어 구성 요소를 사용합니다.
MX 시리즈 라우터 8개.
Junos OS 모든 디바이스에서 릴리스 17.2 이상 실행 중입니다.
SPRING에서 접두사 세그먼트를 구성하기 전에 라우팅 및 신호 전송 프로토콜을 구성해야 합니다.
개요
Junos OS 릴리스 17.2 이상에서는 정책을 구성하여 IS-IS에 보급되는 접두사에 접두사 세그먼트 식별자(SID) 및 노드 SID를 제공할 수 있습니다. 접두사 세그먼트 인덱스는 특정 접두사에 할당된 인덱스입니다. 이는 네트워크의 다른 모든 원격 라우터에서 접두사들을 해당 세그먼트 라우팅 글로벌 블록(SRGB)으로 인덱싱하여 세그먼트 식별자를 도출하고 이 접두사로 향하는 트래픽을 포워딩하는 데 사용됩니다. 접두사 SID는 IPv4 및 IPv6 접두사 모두를 지원합니다. IGP 애니캐스트 세그먼트는 라우터 집합을 식별하는 IGP 접두사 세그먼트입니다. 애니캐스트 세그먼트 또는 애니캐스트 SID는 애니캐스트 세트의 가장 가까운 노드로 향하는 equal-cost multipath-aware shortest-path를 기반으로 포워딩을 적용합니다. 애니캐스트 그룹 내에서 모든 라우터는 동일한 SID 값을 가진 동일한 접두사에 대해 광고합니다. IS-IS 프로토콜은 인접성, 수준 및 주소 패밀리(각각 IPv4 및 IPv6용)당 Adjacency Segment를 생성합니다.
토폴로지
그림 1은 라우터 R0에서 R7까지 SPRING에서 구성된 SRGB, 접두사 세그먼트 및 Adjacency Hold Time을 보여줍니다.
구성
CLI 빠른 구성
이 예를 빠르게 구성하려면, 아래 명령을 복사하여 텍스트 파일로 붙여 넣은 다음 모든 라인브러브를 제거하고, 네트워크 구성을 일치하는 데 필요한 세부 사항을 바꾸고 계층 수준에서 명령을 CLI [edit] 로 복사해 붙여 넣은 다음, 구성 모드에서 을(를) 입력 commit 합니다.
참고:
이 토폴로지에서 IPv4 접두사 시연. IPv6 접두사에도 동일한 것이 적용됩니다.
