clear dhcpv6 relay binding
Syntax
clear dhcpv6 relay binding<address><all><dual-stack><interface interface-name><interfaces-vlan><interfaces-wildcard><logical-system logical-system-name><routing-instance routing-instance-name>
Description
Clear the binding state of Dynamic Host Configuration Protocol for IPv6 (DHCPv6) clients from the client table.
Options
| address | (Optional) Clear the binding state for the DHCPv6 client, using one of the following entries:
|
| all | (Optional) Clear the binding state for all DHCPv6 clients. |
| dual-stack | (Optional) Clear the binding state for DHCPv6 clients and the associated DHCPv4 bindings in the single-session DHCP dual stack. DHCPv4 clients created in a DHCPv4-only stack are not affected. |
| interfaces-vlan | (Optional) Clear the binding state on the interface VLAN ID and S-VLAN ID. |
| interfaces-wildcard | (Optional) The set of interfaces on which to clear bindings. This option supports the use of the wildcard character (*). |
| interface interface-name | (Optional) Clear the binding state for DHCPv6 clients on the specified interface. |
| logical-system logical-system-name | (Optional) Clear the binding state for DHCPv6 clients on the specified logical system. |
| routing-instance routing-instance-name | (Optional) Clear the binding state for DHCPv6 clients on the specified routing instance. |

clear dhcpv6 relay binding all
The following command clears all DHCP relay agent bindings:
user@host> clear dhcpv6 relay binding all
clear dhcpv6 relay binding dual-stack all
The following command clears all DHCPv6 relay agent bindings for all DHCPv6 clients and the associated DHCPv4 bindings in the single-session DHCP dual stack. DHCPv4 clients created in a DHCPv4-only stack are not affected.
user@host> clear dhcpv6 relay binding dual-stack all
clear dhcv6p relay binding interface
The following command clears DHCPv6 relay agent bindings on a specific interface:
user@host> clear dhcpv6 relay binding interface fe-0/0/2
clear dhcpv6 relay binding <interfaces-vlan>
The following command uses the interfaces-vlan option to clear all DHCPv6 relay agent bindings on top of the underlying
interface ae0, which clears DHCPv6 bindings on all demux
VLANs on top of ae0:
user@host> clear dhcpv6 relay binding interface ae0
clear dhcpv6 relay binding <interfaces-wildcard>
The following command uses the interfaces-wildcard option to clear all DHCPv6 relay agent bindings over a specific interface:
user@host> clear dhcpv6 relay binding ge-1/0/0.*
