Figure 1-2 Convert a MAC address into an EUI-64 interface identifier 

 

 

z 

Tunnel interfaces: The lower 32 bits of the interface identifier are the source IPv4 address of the 

tunnel interface. The higher 32 bits of the interface identifier of an ISATAP tunnel interface are 

0000:5EFE, while those of other tunnel interfaces are all zeros. For more information about tunnels, 

refer to Tunneling Configuration in the IP Services Volume.  

z 

Other interfaces (such as serial interface): The interface identifier is generated randomly by the 

device.  

The IPv6 Neighbor Discovery Protocol (NDP) uses five types of ICMPv6 messages to implement the 

following functions: 

z 

Address resolution

 lists the types and functions of ICMPv6 messages used by the NDP. 

Table 1-3 Types and functions of ICMPv6 messages 

Used to acquire the link-layer address of a neighbor 

Used to verify whether the neighbor is reachable 

Neighbor solicitation (NS) 
message 

135 

Used to perform a duplicate address detection 

Used to respond to an NS message 

Neighbor advertisement 
(NA) message 

136 

When the link layer changes, the local node initiates an 
NA message to notify neighbor nodes of the node 
information change. 

Router solicitation (RS) 
message 

133 

After started, a node sends an RS message to request 
the router for an address prefix and other configuration 
information for the purpose of autoconfiguration. 

Used to respond to an RS message 

Router advertisement 
(RA) message 

134 

With the RA message suppression disabled, the router 
regularly sends an RA message containing information 
such as prefix information options and flag bits.
