소개

일부 환경에서는 여러 직렬 링크를 번들로 묶어서 통합 대역폭이 있는 단일 링크로 작동해야 할 수도 있습니다. 이 문서에서는 가상 템플릿 인터페이스를 사용하여 4개의 직렬 인터페이스를 번들링하도록 Cisco 4500 라우터를 구성하는 방법에 대해 설명합니다.

이 구성은 CSU/DSU(Channel Service Unit/Data Service Unit)가 있는 임대 회선 또는 라우터를 통해 연결된 라우터에 사용할 수 있습니다. 필요에 따라 이 구성에 추가 기능을 추가할 수 있습니다.

위의 컨피그레이션을 구현하려면 다음을 구성합니다.

멀티링크 가상 템플릿
인터페이스 가상 템플릿
번들링을 수행해야 하는 각 직렬 인터페이스의 PPP 멀티링크
IP 라우팅 프로토콜로서 RIP

인터페이스 루프백 0은 실패하지 않도록 구성되며, IP unnumbered 루프백 0은 동일한 IP 주소를 가진 5개 이상의 직렬 인터페이스의 번들링을 향상시킵니다.

모든 직렬 인터페이스가 작동되고 사용자 트래픽이 전송될 때 멀티링크 PPP는 가상 액세스 인터페이스를 만들고 PPP 협상이 이루어집니다. 이 가상 액세스 인터페이스의 컨피그레이션은 가상 템플릿에서 복제됩니다. 작동 중인 직렬 인터페이스의 수는 이 가상 액세스 인터페이스에 번들로 제공되며 총 대역폭이 생성됩니다.

다음을 확인합니다.

이 섹션에서는 컨피그레이션이 제대로 작동하는지 확인하는 데 사용할 수 있는 정보를 제공합니다.

일부 show 명령은 출력 인터프리터 툴 에서 지원되는데(등록된 고객만), 이 툴을 사용하면 show 명령 출력의 분석 결과를 볼 수 있습니다.
