config ipv6 nd ra
Description Configures the router advertisement related parameters.
Parameters
ipif_name - The name of the interface.
state - Router advertisement state.
life_time - Indicates the lifetime of the router as the default router in seconds.
reachable_time - Indicates the amount of time that a node can consider a neighboring node
reachable after receiving a reachability confirmation in milliseconds.
retrans_time - Indicates the amount of time between retransmissions of router advertisement
messages in milliseconds, where the router advertisement packet will be taken to it’s host.
If the value user configured is less than 1000ms, the device will send RA with that value, but
the device’s(which received RA) retransmission time of NS messages will use 1000ms
instead of it.
If the value user configured is large than 1000ms, the device will send RA with that value,
and the device’s(which received RA) retransmission time of NS messages will also use that
value.
hop_limit - Indicates the default value of the hop limit field in the IPv6 header for packets sent
by hosts that receive this RA message.
managed_flag - When set to enable, it indicates that hosts receiving this RA must use a
stateful address configuration protocol to obtain an address, in addition to the addresses
derived from the stateless address configuration.
other_config_flag - When set to enable, it indicates that hosts receiving this RA must use a
stateful address configuration protocol to obtain on-address configuration information,.
min_rtr_adv_interval - The minimum time allowed between sending unsolicited multicast
Router Advertisements from the interface, in seconds. MUST be no less than 3 seconds and
no greater than .75 * MaxRtrAdvInterval. Default: 0.33 * MaxRtrAdvInterval.
max_rtr_adv_interval - The maximum time allowed between sending unsolicited multicast
Router Advertisements from the interface, in seconds. MUST be no less than 4 seconds and
no greater than 1800 seconds. Default: 600 seconds.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the RA state as enabled and the life_time of the “triton” interface to be 1000 seconds:
DGS-3627:admin#config ipv6 nd ra ipif triton state enable life_time 1000
Command: config ipv6 nd ra ipif triton state enable life_time 1000
Success.
DGS-3627:admin#
config ipv6 nd ra prefix_option
Purpose Configures the prefix option for the router advertisement function.
Syntax
config ipv6 nd ra prefix_option ipif <ipif_name 12> <ipv6networkaddr>
{preferred_life_time <sec 0-4294967295> | valid_life_time <sec 0-4294967295> |
on_link_flag [enable | disable] | autonomous_flag [enable | disable]} (1)
Description Configures the prefix option for the router advertisement function.
Parameters
ipif_name - The name of the interface.
preferred_life_time - Indicates the number of seconds that an address, based on the
specified prefix using the stateless address configuration, remains in preferred state. For an
infinite valid lifetime the value can be set to 0xffffffff.
valid_life_time - Indicates the number of seconds that an address, based on the specified
prefix, using the stateless address configuration, remains valid. For an infinite valid lifetime
