Virtual Router에서 Edge Uplink IP Address를 이용하여 Ping 테스트

BGP 설정

Virtual Router에서 BGP 설정부터 진행

Tier-0 Gateway 입장에서 Local AS는 Default인 65000으로 놔두고, Virtual Router 쪽은 설정 시 65002를 이용

ADD BGP NEIGHBOR

• IP Address : 192.168.12.1
• Remote AS number : 65002
• Source Addresses : 192.168.12.11, 192.168.12.12

Status가 Success로 변경되는지 확인

 

Virtual Router에서 BPG 정보 다시 확인

## 기존 정보와 비교해보면 Tier-0 Gateway에서 BGP 설정을 하기 전에는 아래 명령어의 결과 중 Up/Down Column이 Never 였으나, Tier-0 Gateway 쪽 설정 후에는 시간이 표시되는 것을 알 수 있음

Redistribution 설정

## Tier-0 Gateway 하위에 생성된 Segment에 대한 Route 정보를 상위 Router에 Advertise 하는 기능

## Tier-1 Gateway도 생성하게 되면 동일하게 Redistribution 설정 필요

Networking > Tier-0 Gateways > Edit Tier0-01 > ROUTE RE-DISTRIBUTION > Route Re-distribution > Set

 

ADD ROUTE RE-DISTRIBUTION

Name : tier0-01-Redistribution

Route Re-distribution Column 밑에 Set 클릭
