설명
라우터 또는 스위치에서 DHCP(Dynamic Host Configuration Protocol) 로컬 서버 옵션을 구성하여 라우터 또는 스위치가 확장된 DHCP 로컬 서버로 작동할 수 있도록 합니다. DHCP 로컬 서버는 DHCP 클라이언트로부터 DHCP 요청 및 응답 패킷을 받은 다음 IP 주소 및 기타 선택적 구성 정보를 사용하여 클라이언트에 응답합니다.
확장된 DHCP 로컬 서버는 J 시리즈 라우터의 DHCP 서버와 호환되지 않으므로 J 시리즈 라우터에서는 지원되지 않습니다. 또한 계층 수준에서 구성된 [edit forwarding-options helpers] DHCP 로컬 서버 및 DHCP/BOOTP 릴레이 서버는 라우터 또는 스위치에서 동시에 활성화될 수 없습니다. 확장된 DHCP 로컬 서버는 확장된 DHCP 릴레이 기능과 완벽하게 호환됩니다.
dhcpv6 스탠자는 DHCPv6(Dynamic Host Configuration Protocol for IPv6)을 지원하도록 라우터 또는 스위치를 구성합니다. DHCPv6 로컬 서버는 확장된 DHCP 로컬 서버 및 확장된 DHCP 릴레이 기능과 완벽하게 호환됩니다.
참고:
라우팅 인스턴스 계층 수준에서 명령문을 구성할 dhcp-local-server 때는 의 라우팅 인스턴스 유형을 virtual-router사용해야 합니다.
나머지 진술은 별도로 설명됩니다. CLI Explorer 에서 문을 검색하거나 Syntax(구문) 섹션에서 연결된 문을 클릭하여 자세한 내용을 확인합니다.
