ipv6 nd ra-dns-server
ipv6 nd ra-dns-server
Advertises the recursive Domain Name System (DNS) server address and the lifetime multiplier
information to IPv6 hosts in the Router Advertisement (RA) message. The no form of this command
disables the advertisement of the specified server address in the RA message.
Syntax ipv6 nd ra-dns-server ipv6-address [lifetime-multiplier decimal]
no ipv6 nd ra-dns-server ipv6-address [lifetime-multiplier decimal]
Command
Default
By default, the recursive DNS server address and the lifetime multiplier information is not
configured.
Parameters ipv6-address Specifies the global IPv6 address of the DNS server.
lifetime-multiplier decimal
Specifies the percentage value of maximum router advertisement interval.
The maximum router advertisement interval is the maximum time that can be
allowed between sending unsolicited RA messages for DNS name resolution.
The lifetime-multiplier decimal value is calculated as percentage of the RA
lifetime. The maximum router advertisement interval percentage range is
100 through 200% and the default value is 200%.

Usage
Guidelines
You can configure a maximum of four recursive DNS server addresses and corresponding lifetime
multiplier values at a given instance.
NOTE
The ipv6 nd ra-dns-server command at the interface configuration level takes precedence over
global configuration. In other words, if at least one DNS server address is configured on an interface,
it will override other DNS server address configurations at the global configuration.
Examples The following examples configure the recursive DNS address for a lifetime-multiplier value of 200.
Brocade(config)# ipv6 nd ra-dns-server 2001:DC8:200::3 lifetime 200
Brocade(config-if-e10000-1/10)# ipv6 nd ra-dns-server 2001:DC8:200::3 lifetime
200
