To configure the relay function:
-
Configure VLANs 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 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 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.
