Release Information

Statement introduced in Junos OS Release 11.4.

Statement introduced in Junos OS Release 12.3 for EX Series switches.

Description

Configure DHCPv6 relay options on the router or switch and enable the router or switch to function as a DHCPv6 relay agent. A DHCPv6 relay agent forwards DHCPv6 request and reply packets between a DHCPv6 client and a DHCPv6 server.

The DHCPv6 relay agent server is fully compatible with the extended DHCP local server and DHCP relay agent. However, the options configured with the dhcpv6 statement are incompatible with the DHCP/BOOTP relay agent options configured with the bootp statement. As a result, the DHCPv6 relay agent and the DHCP/BOOTP relay agent cannot be enabled on the router or switch at the same time.

The remaining statements are explained separately.

Required Privilege Level
