To do...
Disable the RA
message
suppression
Configure the
maximum and
minimum intervals for
sending RA
messages
Configure the prefix
information in RA
messages
Set the M flag bit to 1
Set the O flag bit to 1
Configure the router
lifetime in RA
messages
Set the NS
retransmission timer
Set the reachable
time
The maximum interval for sending RA messages should be less than or equal to the router lifetime in
RA messages.
Use the command...
undo ipv6 nd ra halt
ipv6 nd ra interval
max-interval-value
min-interval-value
ipv6 nd ra prefix
{ ipv6-address prefix-length |
ipv6-address/prefix-length }

Remarks
Required
By default, RA messages are suppressed.
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 random
intervals 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 for 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
1800 seconds by default.
Optional
By default, the local interface sends NS
messages at an interval of 1000
milliseconds, and the value of the Retrans
Timer field in RA messages sent by the
local interface is 0.
Optional
By default, the neighbor reachable time on
the local interface is 30000 milliseconds,
and the value of the Reachable Timer field
in RA messages is 0.
