Configuring IPv6 ND

Configuring a Static Neighbor

A neighbor relationship can be established between a local device and its neighbor after a neighbor is manually configured.

Configuring RA Message Advertisement

If no limit is set on RA message advertisement, a device periodically advertises RA messages, which contain the prefix option and flag bits, to announce the existence of itself.

Setting the Interval for Advertising RA Messages

The device periodically sends Router Advertisement (RA) messages containing information such as prefixes and flag bits.

Configuring the Address Prefixes to Be Advertised

Nodes of the local links can perform address auto-configuration by using prefixes of these addresses.

Configuring Other Information to Be Advertised

Configure other information to be advertised, including the hop limit, life duration of RA messages, times to send DAD messages, interval for re-sending NS messages, NUD reachable time, and MTU of the interface.

Configuring the Default Router Priority and Route Information

Router Advertisement (RA) messages that carry the default router priority and route information can be transmitted over the local link. In this manner, a proper router can be selected to forward the messages of a host.

Enabling IPv6 ND Strict Learning

This section describes how to enable IPv6 neighbor discovery (ND) strict learning to comply with RFC 4861.

Setting an Aging Time for Neighbor Entries in the Stale State

This section describes how to set an aging time for neighbor entries in the stale state. A short aging time allows the device to delete neighbor entries in the stale state quickly.
