Frame Relay 멀티포인트 + RIP 라우팅 구축

2026년 6월 1일 · 1분 분량

1. DLCI 설계 (풀메시 PVC)

구간	한쪽 DLCI	반대쪽 DLCI
R0 ↔ R1	102	201
R0 ↔ R2	103	301
R1 ↔ R2	203	302

2. Cloud0 설정 (GUI)

Config → INTERFACE
- Serial0 : DLCI 102 Add, 103 Add
- Serial1 : DLCI 201 Add, 203 Add
- Serial2 : DLCI 301 Add, 302 Add
Config → CONNECTIONS → Frame Relay (여기서 PVC를 짝지어야 실제 연결됨)
- Serial0 102 ↔ Serial1 201
- Serial0 103 ↔ Serial2 301
- Serial1 203 ↔ Serial2 302
