ACI Multicast 구성 가이드

W
Woo Hyung Choi

The document provides instructions for configuring multicast routing on ACI. It includes 9 steps: 1) enable multicast on the tenant, 2) create a multicast bridge domain, 3) create an IGMP policy, 4) create additional IGMP policies, 5) create an L3 interface policy for border leafs, 6) create an IGMP policy for border leafs, 7) create a PIM policy for border leafs, 8) configure an RP, and 9) verify the multicast configuration. The document also provides CLI commands for troubleshooting multicast routing and lists some limitations.

#1. Multicast Enable 1 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • Multicast Enable
#2. Multicast Bridge Domain 생성 (Internal LEAF 내부 구성) 2 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • Multicast를 사용할 Bridge Domain을 추가
#3. Multicast IGMP Policy 생성 3 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • IGMP Policy 생성 Control Parameter 선택 IGMPv2 또는 IGMPv3 선택 기타 Parameter 선택
#4. Multicast IGMP Policy 생성 4 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • IGMP Policy 생성 Control Parameter 선택 IGMPv2 또는 IGMPv3 선택 기타 Parameter 선택
#5. Multicast L3 Interface Policy 생성 (Border LEAF 구성) 5 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • L3 Out 인터페이스 그룹 선택 • L3 Out 인터페이스 그룹을 위한 IGMP Policy 및 PIM Policy 선택 [ 주의 ] PIM Interface는 Routed Interface만 구성이 가능함 !!! L3 Outside Interface Type 중 SVI Interface에서는 지원하지 않음
#6. Multicast IGMP Policy 생성 (Border LEAF 구성) 6 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • L3 Out 인터페이스 그룹 선택 • L3 Out 인터페이스 그룹을 위한 IGMP Policy 및 PIM Policy 선택 • IGMP Policy 생성 IGMP Interface Policy Name 생성 Control Parameter 구성 IGMP version 선택 기타 Parameters 구성
#7. Multicast PIM Policy 생성 (Border LEAF 구성) 7 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • L3 Out 인터페이스 그룹 선택 • L3 Out 인터페이스 그룹을 위한 IGMP Policy 및 PIM Policy 선택 • PIM Policy 생성 PIM Policy Name 생성 Control Parameter 구성 기타 Parameters 구성
#8. Multicast RP 구성 8 Tenant – “Multicast-Tenant”- Networking-VRF –”VRF”-Multicast • RP 구성 Static RP 또는 Auto-RP 구성
#9. Multicast Policy 적용 확인
Multicast Routing 제약 사항 1 EX만 PIM Routing 지원 (Non EX 모델은 지원하지 않음) 2 L3 Outside Interface에서 SVI Interface는 PIM Routing을 지원하지 않음 3 PIM을 사용하는 BD를 위해 IGMP Snooping을 반드시 설정해야 함. 4 Multicast 제어를 위한 Contract 구성은 불가
