27.4 Configuring IPv6 neighbor discovery protocol

27.4.1 Configuring the parameters of the RA message

The user can configure the interface whether to send RA messages and send RA messages

according to the actual situation, and configure the related parameters in the RA message to notify

the host. When the host receives the RA message, we can use these parameters to do the

corresponding operation。The parameters and meanings of configurable RA messages are shown in

table 1-4。

Table 1-4 parameters and descriptions in RA message

parameter

describe

Cur Hop Limit

When the host sends the IPv6 message, it will fill the Hop Limit

field in the IPv6 header with the parameter value. At the same

time, the parameter value is also used as the Hop Limit field

value in the device reply message

。

Prefix Information

When the host on the same link receives the prefix information

of the device, it can perform stateless automatic configuration

and other operations

。

M flag

To determine whether the host uses stateful automatic

configuration to obtain the IPv6 address。

If this flag is set to 1, the host will have state through automatic

configuration (e.g. DHCP server) to obtain IPv6 address;

otherwise, the stateless auto configuration to obtain IPv6

address, IPv6 address is generated according to their link layer

address and router prefix information release

。

O flag

To determine whether the host uses stateful automatic

configuration to obtain additional information other than the

IPv6 address。

If you set the other configuration flag is 1, the host will have

state through automatic configuration (e.g. DHCP server) to

obtain information in addition to other IPv6 address; otherwise,

the stateless auto configuration for additional information

。

Router Lifetime

The time used to set the router that releases the RA message as

the default router for the host. According to the router survival

time parameter value in the received RA message, the host can

determine whether or not the router that publishes the RA

message will be the default router

。

Retrans Timer

When the device sends NS messages, the NS message is re sent

if the response is not received within the specified time interval

。

Reachable Time

When the neighbor unreachability detection to verify that a

neighbor, in time up to set, equipment up to that neighbor;

exceed the time set, if you need to send messages to neighbors,

neighbors will re confirm whether can reach

。

Link MTU

The MTU option is used in the RA message to ensure that all
