이 문서의 정보는 아래 소프트웨어 및 하드웨어 버전을 기반으로 합니다.
Cisco IOS Software 릴리스 12.1(3)을 실행하는 Cisco 3640
Cisco IOS Software 릴리스 12.07(T)을 실행하는 Cisco AS5300
참고: MP는 Cisco IOS Software 릴리스 11.0(3)에서 처음 도입되었습니다.
이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 라이브 네트워크에서 작업하는 경우, 사용하기 전에 모든 명령의 잠재적인 영향을 이해해야 합니다.
문서 규칙에 대한 자세한 내용은 Cisco 기술 팁 표기 규칙을 참조하십시오.
MP(Multilink PPP)를 사용하면 가상 링크를 구현하여 여러 포인트-투-포인트 데이터 링크를 통해 동일한 대상에 데이터를 전송할 수 있습니다. MP 연결의 최대 대역폭은 구성 요소 링크의 대역폭 합계와 같습니다. MP는 ISDN 및 프레임 릴레이와 같은 멀티플렉싱 링크 또는 여러 비동기 회선에 대해 구성할 수 있습니다. MP에 대한 자세한 내용은 RFC 1990 을 참조하십시오.
참고: RFC 1990은 Multilink PPP를 MP로 참조합니다. MP가 알려진 다른 이름은 MPPP, MLP 및 Multilink입니다.
비동기 MP를 사용하여 단일 아날로그 연결을 통해 사용할 수 있는 속도보다 빠른 속도로 원격 클라이언트를 연결할 수 있습니다. Async MP에서 원격 클라이언트는 여러 모뎀을 사용하므로 여러 전화선을 사용하여 중앙 라우터에 전화를 걸어 네트워크에 액세스합니다. 여러 전화 회선이 ISDN BRI(Basic Rate Interface) 서비스보다 저렴한 경우가 많으므로 Async MP는 원격 사용자의 연결 속도를 높이는 동시에 비용을 제어하는 효과적인 방법을 제공합니다. Async MP는 ISDN에서 서비스할 수 없는 원격 영역에 대해 더 높은 액세스 속도를 얻는 효과적인 방법입니다.
Async MP는 Access Server에 대한 별도의 모뎀 연결을 함께 번들링합니다. 각 피어의 PPP 소프트웨어는 패킷을 프래그먼트한 다음 여러 아날로그 연결을 통해 조각을 다른 편으로 전송합니다. 수신 엔드에서는 별도의 연결에서 이러한 조각을 수집하고, 여기에 포함된 MP 정보를 기반으로 조각이 유효한 데이터 패킷으로 리어셈블되므로 대역폭이 더 높은 엔드 투 엔드 가상 링크를 제공합니다. 두 라우터 간에 또는 라우터와 클라이언트 PC 간에 비동기 MP를 구성할 수 있습니다.

다음 명령을 사용하여 MP 연결의 동작을 조정할 수 있습니다. 이러한 매개 변수를 신중하게 조정하면 데이터 링크의 낭비나 불필요한 사용을 방지하여 비용을 관리하는 데 도움이 됩니다.
다이얼러 로드 임계값 로드 [아웃바운드 | 인바운드 | 또는]
MP를 구성하여 기본 채널이 설정된 후 즉시 추가 채널이 생성되도록 할 수 있습니다. 이 시나리오를 설정하려면 다이얼러 load-threshold load 명령의 로드 임계값을 1로 설정합니다. 이 경우 추가 채널이 가동되어 계속 작동합니다(즉, 플랩되지 않음). 로드 임계값이 다른 값으로 설정된 경우 링크 전체의 로드에 따라 여러 채널이 플랩될 수 있습니다. 필요에 따라 추가 채널을 추가하려는 경우 트래픽에 따라 load-threshold를 1~255 사이의 적절한 값으로 설정합니다. 예를 들어, 추가 채널이 50%로 증가하려면 임계값을 128(0.50*255)로 설정해야 합니다. 임계값을 결정할 때 설정 시간이 길수록 임계값이 낮아질 수 있으므로 비동기 통화의 설정 시간을 고려해야 합니다.
부하는 아웃바운드, 인바운드 또는 인터페이스에서 인바운드 또는 아웃바운드 트래픽의 상위를 기준으로 계산할 수 있습니다. 인바운드 또는 둘 중 하나를 기준으로 하는 경우 코어의 라우팅 업데이트가 비동기 라인을 통해 전송되지 않도록 중앙 사이트에 패시브 인터페이스 Group-Async1이 구성되어 있는지 확인합니다. 라우팅 트래픽이 링크에서 전달되지 않도록 하면 회선의 다른 데이터에 더 많은 대역폭이 제공됩니다.
ppp timeout multilink 제거 초
로드가 다를 때 멀티링크 연결이 플래핑되지 않도록 하는 데 이 명령을 사용할 수 있습니다. 예를 들어, 로드 임계값이 15(즉, 15/255=6%)로 설정되고 트래픽이 임계값을 초과하면 추가 행이 표시됩니다. 트래픽이 임계값 아래로 떨어지면 추가 행이 삭제됩니다. 데이터 속도가 매우 가변적인 경우 로드 임계값이 지정된 값보다 낮더라도 여러 채널이 지정된 기간 동안 유지되도록 하는 것이 좋습니다. 이 멀티링크 시간 초과는 모든 링크의 시간 제한을 제어하는 다이얼러 유휴 시간 제한에 지정된 시간보다 작도록 할당합니다.
ppp timeout multilink 추가 초
이 명령을 사용하면 지정된 간격으로 높은 트래픽이 수신될 때까지 여러 링크가 MP 번들에 추가되지 않도록 할 수 있습니다. 이로 인해 트래픽이 폭발적으로 증가하여 추가 회선이 불필요하게 발생하는 것을 방지할 수 있습니다.
이 섹션에서는 컨피그레이션이 제대로 작동하는지 확인하는 데 사용할 수 있는 정보를 제공합니다.
특정 show 명령은 show 명령 출력의 분석을 볼 수 있는 출력 인터프리터 도구에서 지원됩니다.
show ppp multilink - 활성 상태인 멀티링크 번들에 대한 정보를 표시합니다. 이 명령을 사용하여 멀티링크 연결을 확인해야 합니다.
show caller - NAS에서 개별 사용자 및 사용된 리소스에 대한 정보를 표시합니다. 이 명령은 대규모 연결 풀에 대한 활성 통화 통계를 표시하고 각 사용자에 대한 절대 및 유휴 시간을 표시합니다. 사용 중인 버전의 Cisco IOS 소프트웨어가 이 명령을 지원하지 않는 경우 show user 명령을 사용합니다.
