RemarksEnter system view system-view —Configure a staticneighbor entryipv6 neighbor ipv6-address mac-address { vlan-idport-type port-number | interface interface-typeinterface-number }RequiredYou can adopt either of the two methods above to configure a static neighbor entry.z After a static neighbor entry is configured by using the first method, the device needs to resolve thecorresponding Layer 2 port information of the VLAN interface.z If you adopt the second method, you should ensure that the corresponding VLAN interface existsand that the Layer 2 port specified by port-type port-number belongs to the VLAN specified byvlan-id. After a static neighbor entry is configured, the device relates the VLAN interface to the IPv6address to uniquely identify a static neighbor entry.Configuring the Maximum Number of Neighbors Dynamically LearnedThe device can dynamically acquire the link-layer address of a neighbor node through NS and NAmessages and add it into the neighbor table. Too large a neighbor table may reduce the forwardingperformance of the device. You can restrict the size of the neighbor table by setting the maximumnumber of neighbors that an interface can dynamically learn. When the number of dynamically learnedneighbors reaches the threshold, the interface will stop learning neighbor information.Follow these steps to configure the maximum number of neighbors dynamically learned:To do… Use the command… RemarksEnter system view system-view —Enter interface view interface interface-typeinterface-number —Configure the maximum number ofneighbors dynamically learned by aninterfaceipv6 neighborsmax-learning-num numberOptionalThe default value is 1024.Configuring Parameters Related to RA MessagesYou can enable an interface to send RA messages, and configure the interval for sending RA messagesand parameters in RA messages. After receiving an RA message, a host can use these parameters toperform corresponding operations. Table 1-4 lists the configurable parameters in an RA message andtheir descriptions.
