Remarks
Optional
By default, the maximum
interval for sending RA
messages is 600
seconds, and the
minimum interval is 200
seconds.
The device sends RA
messages at intervals of a
random value between
the maximum interval and
the minimum interval.
The minimum interval
should be less than or
equal to 0.75 times the
maximum interval.
Optional
By default, no prefix
information is configured
in RA messages and the
IPv6 address of the
interface sending RA
messages is used as the
prefix information.
Optional
By default, the M flag bit is
set to 0, that is, hosts
acquire IPv6 addresses
through stateless
autoconfiguration.
Optional
By default, the O flag bit is
set to 0, that is, hosts
acquire other information
through stateless
autoconfiguration.
Optional
1,800 seconds by default.
Optional
By default, the local
interface sends NS
messages at intervals of
1,000 milliseconds and
the Retrans Timer field in
RA messages sent by the
local interface is equal to
0.
