Information
You can use this command to enable programming of /128 route prefixes in L3 host table or in LPM table.
A warning message is displayed when you enter this command stating that this setting takes effect for

programming of /128 route prefixes in LPM table, use no ipv6 unicast-host-route command.

Dell(conf)#
ipv6 nd dns-server
Configures Recursive DNS Server (RDNSS) addresses to be distributed via IPv6 router advertisements to an IPv6 device.
Syntax
ipv6 nd dns-server {ipv6-RDNSS-address} {lifetime | infinite}
To remove the IPv6 RDSS configuration, use no ipv6 nd dns-server {ipv6-RDNSS-address}
{lifetime | infinite}
Parameters
ipv6-RDNSS-
address
Enter the IPv6 Recursive DNS Server’s (RDNSS) address. You can specify up to 4
IPv6 RDNSS server addresses.
lifetime Enter the lifetime in seconds. The amount of time the IPv6 host can use the IPv6
RDNSS address for name resolution. The range is 0 to 4294967295 seconds.
When you specify the maximum lifetime value of 4294967295 or infinite, the
lifetime does not expire. A value of 0 indicates to the host that the RDNSS address
should not be used. You must specify a lifetime using the lifetime or
infinite parameter.
infinite Enter the keyword infinite to specify that the RDNSS lifetime does not expire.
