Parameters
client-ip: Specifies the IP address to be released.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance of the IP address. The
vpn-instance-name is a case-sensitive string of 1 to 31 characters. If you do not specify any VPN instance,
this command releases the IP address in the public network.
Usage guidelines
After you execute this command, the relay agent sends a DHCP-RELEASE packet to the DHCP server and
removes the relay entry of the IP address. Upon receiving the packet, the server removes binding
information for the specified IP address to release the IP address.
Examples
# Release the IP address 1.1.1.1.
<Sysname> system-view
[Sysname] dhcp relay release ip 1.1.1.1
