Demand Circuit
- 주기적으로 전달하는 Hello 패킷 및 30분마다 전송하는 LSA 패킷을 억제
- LSA Reflesh 방지에 유용
--> - Point to Point 또는 Point to Multipoint 인터페이스에서 설정이 가능하다.
- Virtual Link 설정시 자동으로 설정된다.
- 멀티엑세스 인터페이스에서 설정 가능하다.
Demand Circuit Refresh 전송 시기
- 네트워크 토폴로지의 변경
- OSPF Demand Circuit을 이해 불가능한 라우터가 존재하는 경우
설정 명령어
1. 설정
conf t
int [가상 인터페이스]
ip ospf demand-circuit
한쪽 인터페이스에만 설정해도 상대 인터페이스에도 적용이 됨.
2. 확인
show ip ospf interface [가상 인터페이스]
