Usage Information You can use this command to enable programming of /128 route prexes in L3 host table or in LPM table. A
warning message is displayed when you enter this command stating that this setting takes eect for existing
routes only when IPv6 route prexes are cleared from the routing table (RTM). To enable programming of /128
route prexes in LPM table, use no ipv6 unicast-host-route command.
Example
Dell(conf)# ipv6 unicast-host-route
Warning: Command will take effect for existing routes only when IPv6
route prefixes are cleared from RTM
Dell(conf)#no ipv6 unicast-host-route

Dell(conf)#
ipv6 nd dns-server
Congures 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 conguration, 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.
innite Enter the keyword infinite to specify that the RDNSS lifetime does not expire.
Defaults Not Congured
