Describes IPv6 Neighbor Discovery in Cisco ACI and explains how to configure ND policies, router advertisements, and duplicate address detection on bridge domains and Layer 3 interfaces
This chapter contains the following sections:
Neighbor discovery
Facilitates IPv6 address auto-configuration, node discovery, and reachability maintenance within the ACI fabric. This protocol ensures efficient communication and network management across various Layer 3 interfaces.
Create the tenant, VRF, and bridge domain with IPv6 neighbor discovery on the bridge domain using the GUI
Configures a tenant, a VRF, and a bridge domain with IPv6 neighbor discovery interface and prefix policies. This procedure enables the deployment of custom neighbor discovery policies for subnets and interfaces within the APIC environment.
Guidelines and limitations
Describes the operational constraints and requirements for Neighbor Discovery Router Advertisement prefixes on Layer 3 interfaces. These guidelines ensure correct configuration and protocol behavior within the network environment.
Configure an IPv6 neighbor discovery interface policy with RA on a layer 3 interface using the GUI
Configures an IPv6 neighbor discovery interface policy with router advertisement on a Layer 3 interface. This procedure enables the interface for auto configuration using the GUI.
About neighbor discovery duplicate address detection
Describes the Duplicate Address Detection process used by Neighbor Discovery to identify address conflicts within a network. This feature ensures proper IPv6 address management on ACI fabric leaf layer 3 interfaces while allowing for specific configuration overrides to support border leaf redundancy.
Configure neighbor discovery duplicate address detection using the GUI
This topic describes disabling neighbor discovery Duplicate Address Detection for a subnet using the GUI, including interface navigation, DAD parameter configuration, and verifying settings on the leaf switch.
