advertisements to 300 seconds and the router lifetime value to 1900 seconds on Ethernet interface 1/3/1, enter the following
commands.
device(config)#interface ethernet 1/3/1
device(config-if-e1000-1/3/1)#ipv6 nd ra-interval 300
device(config-if-e1000-1/3/1)#ipv6 nd ra-lifetime 1900
device(config-if-e1000-1/3/1)#ipv6 nd ra-hop-limit 1
Here is another example with a specified range.
device(config)#interface ethernet 1/3/1
device(config-if-e1000-1/3/1)#ipv6 nd ra-interval range 33 55
device(config-if-e1000-1/3/1)#ipv6 nd ra-lifetime 1900
device(config-if-e1000-1/3/1)#ipv6 nd ra-hop-limit 1
Syntax: [no] ipv6 nd ra-interval number | min-range-value max-range-value
Syntax: [no] ipv6 nd ra-lifetime number
Syntax: ipv6 nd ra-hop-limit number
number is a value from 0 - 255. The default is 64.
The ipv6 nd ra-interval number 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 min range value max range value command lets you specify a range of values instead of a single value.
The min-range-value specifies the minimum number of seconds allowed between sending unsolicited multicast router advertisements
from the interface. The default is 0.33 times the max-range-value if the max-range-value is greater than or equal to 9 seconds.
Otherwise, the default is the value specified by the max-range-value . The min-range-value can be a number between -3 - (.75 x max
range value ).
The max-range-value 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 min-range-value x
1.33. The default is 600 seconds.
The ipv6 nd ra-lifetime number 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 number 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 .
Prefixes advertised in IPv6 router advertisement messages
By default, router advertisement messages include prefixes configured as addresses on router interfaces using the ipv6 address
command. You can use the ipv6 nd prefix-advertisement command to control exactly which prefixes are included in router
advertisement messages. Along with which prefixes the router advertisement messages contain, you can also specify the following
parameters:
• Valid lifetime --(Mandatory) The time interval (in seconds) in which the specified prefix is advertised as valid. The default is
2592000 seconds (30 days). When the timer expires, the prefix is no longer considered to be valid.
• Preferred lifetime --(Mandatory) The time interval (in seconds) in which the specified prefix is advertised as preferred. The
default is 604800 seconds (7 days). When the timer expires, the prefix is no longer considered to be preferred.
