ipv6 dhcp-ldra attach-policy

dhcp-ldra attach-policy command in interface configuration mode. To disable LDRA functionality on
an interface or port, use the no form of this command.
Syntax Description client-facing-trusted
client-facing-untrusted
client-facing-disable
server-facing
Command Default LDRA functionality is not enabled on an interface or port.
Command Modes Interface configuration (config-if)
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 in global
configuration mode before configuring it on an interface or port.
The ipv6 dhcp-ldra attach-policy command enables LDRA functionality on a specific interface or port.
Instead of configuring LDRA individually on all the client-facing interfaces or ports individually, use
the ipv6 dhcp ldra attach-policy command to configure LDRA on an entire VLAN.
Examples
The following example shows how to enable LDRA functionality on an interface and specify it as server
facing:
Device> enable
Device# configure terminal
Device(config)# ipv6 dhcp-ldra enable
Device(config)# interface gigabitethernet 0/0
Device(config-if)# switchport
Device(config-if)# ipv6 dhcp-ldra attach-policy server-facing
Device(config-if)# exit
