Step 2. Enter interface view. 3. Enable sending of RA messages. Command interface interface-type interface-number undo ipv6 nd ra halt 4. Configure the maximum and ipv6 nd ra interval minimum intervals for sending max-interval-value RA messages. min-interval-value Remarks N/A The default setting is disabled. 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. Configuring parameters for RA messages Step 1. Enter system view. 2. Enter interface view. 3. Configure the prefix information in RA messages. 4. Turn off the MTU option in RA messages. 5. Specify unlimited hops in RA messages. 6. Set the M flag bit to 1. 7. Set the O flag bit to 1. 8. Configure the router lifetime in RA messages. Command Remarks system-view N/A interface interface-type interface-number N/A ipv6 nd ra prefix { ipv6-prefix prefix-length | ipv6-prefix/prefix-length } valid-lifetime preferred-lifetime [ no-autoconfig | off-link ] * 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. If the IPv6 address is manually configured, the prefix uses a fixed valid lifetime of 2592000 seconds (30 days) and a preferred lifetime of 604800 seconds (seven days). If the IPv6 address is automatically obtained, the prefix uses the valid lifetime and preferred lifetime configured for the IPv6 address. ipv6 nd ra no-advlinkmtu By default, RA messages contain the MTU option. ipv6 nd ra hop-limit unspecified By default, the maximum number of hops in RA messages is 64. ipv6 nd autoconfig managed-address-flag By default, the M flag bit is set to 0 and hosts acquire IPv6 addresses through stateless autoconfiguration. ipv6 nd autoconfig other-flag By default, the O flag bit is set to 0 and hosts acquire other configuration information through stateless autoconfiguration. ipv6 nd ra router-lifetime value By default, the router lifetime is 1800 seconds. 130

The default setting is disabled.
4.
Configure the maximum and
minimum intervals for sending
RA messages.
ipv6 nd ra interval
max-interval-value
min-interval-value
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.

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. If the IPv6 address is
manually configured, the prefix uses a
fixed valid lifetime of 2592000 seconds
(30 days) and a preferred lifetime of
604800 seconds (seven days). If the
IPv6 address is automatically obtained,
the prefix uses the valid lifetime and
preferred lifetime configured for the IPv6
address.
4.
Turn off the MTU option in
RA messages.
ipv6 nd ra no-advlinkmtu
By default, RA messages contain the
MTU option.
5.
Specify unlimited hops in
RA messages.
ipv6 nd ra hop-limit
unspecified
By default, the maximum number of hops
in RA messages is 64.
6.
Set the M flag bit to 1.
ipv6 nd autoconfig
managed-address-flag
By default, the M flag bit is set to 0 and
hosts acquire IPv6 addresses through
stateless autoconfiguration.
7.
Set the O flag bit to 1.
ipv6 nd autoconfig other-flag
By default, the O flag bit is set to 0 and
hosts acquire other configuration
information through stateless
autoconfiguration.
8.
Configure the router
lifetime in RA messages.
ipv6 nd ra router-lifetime
value
By default, the router lifetime is 1800
seconds.
