예: 멀티포인트 LDP 재귀 FEC 구성
SUMMARY
주:
당사 콘텐츠 테스트 팀은 이 예제를 검증하고 업데이트했습니다.
이 구성 예를 사용하여 OSPF 네트워크에서 LDP(Multipoint Label Distribution Protocol) FEC(Recursive Forwarding Equivalence Class)를 구성하고 확인합니다. 이를 통해 백본에 루트 노드로 직접 경로가 없는 경우 두 AS(Autonomous System) 간에 MLDP P2MP(Point-to-Multipoint) 터널을 형성할 수 있습니다.

토폴로지 개요
이 구성 예에서는 멀티캐스트 트래픽을 전송할 수 있는 호스트 시스템과 멀티캐스트 트래픽을 수신할 수 있는 호스트 시스템을 보여 줍니다. 두 개의 자율 시스템(AS)을 보여줍니다. PE1, P1 및 ASBR1 라우터와 PE2, P2 및 ASBR2 라우터로 구성된 AS65020 구성된 AS65010. AS 내의 모든 라우터는 OSPF를 IGP로 실행합니다. 모든 라우터는 영역 0에 속합니다. 고객 에지(CE) 디바이스는 EBGP 피어링을 사용하여 레이어 3 VPN 서비스의 일부로 공급자 에지 디바이스와 경로를 교환합니다. PE 디바이스는 IBGP를 사용하여 원격 PE와 IPv4 경로를 교환합니다.
공급자 에지(PE2) 및 AS 경계 라우터(ASBR2) 라우터에는 루트 PE1에 대한 경로가 있습니다. 그러나 P(P1 및 P2) 라우터에는 루트에 대한 경로가 없습니다. MLDP P2MP 터널은 송신(PE2)에서 수신(PE1) 라우터로 형성되어 mLDP를 통해 FEC 요소를 전달합니다.

원격 CE 디바이스. |
EBGP 피어-PE1 라우터를 통해 CE 디바이스 루프백 주소를 보급하고 학습합니다. |
|
|
로컬 PE 디바이스. |
PE1에 대한 직접 경로가 없는 시나리오에서 다른 AS의 중간 라우터가 도달하려고 시도하는 루트 노드입니다. |
|
|
중간 장치 P1. |
PE2 라우터에 대한 경로가 없는 중간 라우터입니다. ASBR1에서 PE1-FEC를 수신하여 일반 LDP P2MP FEC로 처리합니다. |
|
|
AS 경계 라우터 ASBR1 |
EBGP 피어-ASBR2 라우터를 통해 IGP 경로를 보급하고 학습합니다. ASBR1은 루트에 대한 경로(IGP 경로)를 찾고 추가 처리를 수행하기 전에 ASBR1-FEC를 PE1-FEC(Recursive Opaque Value)의 내용으로 대체합니다. |
|
|
AS 경계 라우터 ASBR2 |
EBGP 피어에서 ASBR1 라우터로 IGP 경로를 보급하고 학습합니다. P2의 루트 노드 역할을 하며 실제 루트(PE1)에 대한 경로를 찾기 위해 조회를 수행합니다. PE1에 대한 경로가 BGP 경로인지 확인하고 ASBR1에서 PE1에 LDP 재귀 FEC를 형성합니다. |
|
|
중간 장치 P2. |
PE1 라우터에 대한 경로가 없는 중간 라우터입니다. PE2에서 mLDP를 통해 FEC 요소를 수신합니다. 그러나 PE1에 대한 경로가 없으므로 동일한 FEC 요소를 사용할 수 없습니다. |
|
|
로컬 PE 디바이스. |
PE2는 PE1 주소를 루트 노드 주소로 사용하여 MP FEC 요소를 생성하여 PE2에서 루트 PE1로의 P2MP 터널을 형성합니다. |
|
|
원격 CE 디바이스. |
PE2 라우터에 대한 EBGP 피어링으로 CE 디바이스 루프백 주소를 보급하고 학습합니다. |
