ipv6 dhcp-lrda
ipv6 dhcp-lrda
To enable Lightweight DHCPv6 Relay Agent (LDRA) functionality on an access node, use the ipv6
dhcp-ldra command in global configuration mode. To disable the LDRA functionality, use the no form
of this command.
Syntax Description
enable
disable
remote-id remote-id
Command Default If the remote ID is not configured, a system generated remote ID is used.
Command Modes
Global configuration (config)
Command History Release
Cisco IOS
Release 15.2(5)E2
Usage Guidelines You must configure the LDRA functionality globally using the ipv6 dhcp-ldra command before
configuring it on a VLAN or an access node (such as a Digital Subscriber Link Access Multiplexer
[DSLAM] or an Ethernet switch) interface.
To enable LDRA, configure the ipv6 dhcp-ldra command. To disable LDRA, configure either the no
ipv6 dhcp-ldra enable or the ipv6 dhcp-ldra disable command. Configuring the no ipv6 dhcp-ldra
command will not disable LDRA globally, and as a result, there is no carriage return after the no ipv6
dhcp-ldra command.
Examples
The following example shows how to enable the LDRA functionality:
Device> enable
Device# configure terminal
Device(config)# ipv6 dhcp-ldra enable
Device(config)# exit
