ipv6 dhcp lrda attach-policy (VLAN)
To enable Lightweight DHCPv6 Relay Agent (LDRA) functionality on a VLAN, use the ipv6 dhcp ldra
attach-policy command in VLAN configuration mode. To disable LDRA functionality on a VLAN, use
the no form of this command.
Syntax Description
client-facing-trusted
client-facing-untrusted
Command Default The LDRA functionality is not enabled on a VLAN.
Command Modes VLAN configuration (config-vlan-config)
Command History Release
Cisco IOS
Release 15.2(5)E2
Usage Guidelines You need to configure the LDRA functionality globally using the ipv6 dhcp-ldra command before
configuring it on a VLAN.
In a typical deployment, a majority of the interfaces or ports on a device are client facing. Instead of
configuring LDRA individually on all the client facing interfaces and ports, use the ipv6 dhcp ldra
attach-policy command to configure LDRA on the entire VLAN. As a result, all the ports or interfaces
associated with the VLAN will be configured as client facing.
Examples
The following example shows how to enable LDRA functionality on a VLAN:
Device> enable
Device# configure terminal
Device(config)# ipv6 dhcp-ldra enable
Device(config)# vlan configuration 5
Device(config-vlan-config)# ipv6 dhcp ldra attach-policy client-facing-trusted
Device(config-vlan-config)# exit
