ND Configuration

Overview of ND

ND allows mapping between network-layer IPv6 address and link-layer MAC addresses to ensure communication on an Ethernet.

Configuration Precautions for ND

Configuring IPv6 Neighbor Discovery

IPv6 neighbor discovery (ND) uses a group of messages and processes that identify relationships between neighboring nodes. IPv6 ND contains the same functions of ARP and ICMP router discovery, as well as the additional neighbor reachability detection function.

Configuring Duplicate Address Detection

Duplicate address detection is a process in which a device checks whether the address to be used for an interface has been used by another interface.

Configuring RA

A device periodically sends Router Advertisement (RA) messages that carry prefixes and flag bits, or responds to the router request messages with RA messages.

Configuring IPv6 SEND

The SEcure Neighbor Discovery (SEND) protocol is a security extension of the Neighbor Discovery Protocol (NDP) in IPv6.

Configuring Rate Limiting on ND Messages

Configuring Proxy ND

A device can function as the proxy of a target host to reply to unreachable requests in special scenarios.

Configuring NS Multicast Suppression on an EVPN MPLS

When a user accesses an EVPN MPLS through a BD, NS multicast suppression can be configured to reduce or suppress excess NS messages.

Maintaining ND

This section describes how to clear ND statistics and monitor the ND operating status.
