설명
라우터 또는 스위치에서 확장 DHCP(Dynamic Host Configuration Protocol) 릴레이 및 DHCPv6 릴레이 옵션을 구성하여 라우터(또는 스위치)가 DHCP 릴레이 에이전트로 작동할 수 있도록 합니다. DHCP 릴레이 에이전트는 DHCP 클라이언트와 DHCP 서버 사이에 DHCP 요청 및 응답 패킷을 전달합니다.
DHCP 릴레이는 동적 프로필의 첨부를 지원하고 로컬 AAA 서비스 프레임워크와 상호 작용하여 RADIUS 같은 백엔드 인증 서버를 사용하여 가입자 인증 또는 클라이언트 인증을 제공합니다. 동적 프로필을 첨부하고 글로벌 또는 특정 인터페이스 그룹에 대한 인증 지원을 구성할 수 있습니다.
및 dhcpv6 문으로 구성된 확장 DHCP 및 DHCPv6 릴레이 에이전트 옵션은 문으로 dhcp-relay 구성된 DHCP/BOOTP 릴레이 에이전트 옵션과 bootp 호환되지 않습니다. 그 결과, 확장된 DHCP 또는 DHCPv6 릴레이 에이전트와 DHCP/BOOTP 릴레이 에이전트는 라우터(또는 스위치)에서 동시에 활성화될 수 없습니다.
나머지 문은 별도로 설명됩니다. CLI 탐색 기에서 문을 검색하거나 자세한 내용은 구문 섹션에서 연결된 문을 클릭합니다.
