When adjusting these parameter settings, Brocade recommends that the interval between router
advertisement transmission be less than or equal to the router lifetime value if the router is
advertised as a default router. For example, to adjust the interval of router advertisements to 300
seconds and the router lifetime value to 1900 seconds on Ethernet interface 1/1/1, enter the
following commands.
Brocade(config)#interface ethernet 1/1/1
Brocade(config-if-e10000-1/1/1)#ipv6 nd ra-interval 300
Brocade(config-if-e10000-1/1/1)#ipv6 nd ra-lifetime 1900
Brocade(config-if-e10000-1/1/1)#ipv6 nd ra-hop-limit 1
Here is another example with a specified range.
Brocade(config)#interface ethernet 1/1/2
Brocade(config-if-e10000-1/1/2)#ipv6 nd ra-interval range 33 55
Brocade(config-if-e10000-1/1/2)#ipv6 nd ra-lifetime 1900
Brocade(config-if-e10000-1/1/2)#ipv6 nd ra-hop-limit 1

Syntax: ipv6 nd ra-hop-limit
is a value from 0 – 255. The default is 64.
The ipv6 nd ra-interval can be a value between 3 – 1800 seconds. The default is 200
seconds. The actual RA interval will be from .5 to 1.5 times the configured or default value. For
example, in the above configuration, for ipv6 nd ra-interval 300, the range would be 150 – 450. To
restore the default interval of 200 seconds, use the no form of the command.
The ipv6 nd ra-interval range command lets you specify a
range of values instead of a single value.
The specifies the minimum number of seconds allowed between sending
unsolicited multicast router advertisements from the interface. The default is 0.33 times the
if the is greater than or equal to 9 seconds. Otherwise,
the default is the value specified by the . The can be a
number between -3 – (.75 x ).
The parameter specifies the maximum number of seconds allowed
between sending unsolicited multicast router advertisements from the interface. This number
can be between 4 – 1800 seconds and must be greater than the x 1.33.
The default is 600 seconds.
The ipv6 nd ra-lifetime is a value between 0 – 9000 seconds. To restore the router
lifetime value of 1800 seconds, use the no form of the command.
The ipv6 nd ra-hop-limit is a value from 0 – 255. The default is 64.
NOTE
By default, router advertisements will always have the MTU option. To suppress the MTU option, use
the following command at the Interface level of the CLI: ipv6 nd suppress-mtu-option.
