Configuring DHCPv6 BOOTP Relay

To configure the relay function:

Configure VLAN (Virtual LAN)s and IP unicast routing.

Note
As in DHCPv4, when you create an IPV6 VLAN interface, the corresponding disabledV6VlanList has an entry. The VLAN interface entry is removed whenever the bootpRelayv6 for the respective VLAN is enabled, and vice versa.
Enable the DHCP (Dynamic Host Configuration Protocol) or BOOTP relay function using the following commands:
enable bootprelay {ipv4|ipv6} {vlan[vlan_name] |{vr} vr_name}|all [{vr} vr_name]}

enable bootprelay {vlan[vlan_name] |{vr} vr_name}|all [{vr} vr_name]}
Configure the addresses to which DHCP or BOOTP requests should be directed using the following command:
configure bootreplay {ipv4} | {{vlan}vlan_name} [[add ip_address] | delete [ip_address | all]]] | ipv6 [[add ipv6_address] | [delete ipv6_address | all]]]]] {vr vrid}

configure bootprelay add ip_address {vr vrid}
Note

Use the configure bootprelay ipv6 option interface-id InterfaceIDName vlan {vlan_name} command to set up a unique interface-id. It can be MAC-ID, or port-vlan combination. You can also use this command to set up dhcpv6 server/next hop for each VLAN interface, or across VR. A configuration applied to the VR level is populated to all VLAN V6 interfaces.
To delete an entry, use the following command:
configure bootprelay delete ip_address {vr vrid}
To disable BOOTP relay on one or more VLANs, use the following command
disable bootprelay {ipv4 | ipv6} {vlan [vlan_name] | {{vr} vr_name} | all [{vr} vr_name]}

disable bootprelay {{vlan} [vlan_name] | {{vr} vr_name} | all [{vr} vr_name]}

Note
When VRRP (Virtual Router Redundancy Protocol) and BOOTP/DHCP relay are both enabled on the switch, the relayed BOOTP agent IP address is the actual switch IP address, not the virtual IP address.
