for sending RA messages is 600
seconds, and the minimum interval
is 200 seconds.

3. Configure the prefix
information in RA
messages.
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 (7 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.
