Configuring the IPv6 Recursive DNS Server

You can configure up to four Recursive DNS Server (RDNSS) addresses to be distributed via IPv6 router advertisements to an IPv6 device, using the ipv6 nd dns-server ipv6-RDNSS-address {lifetime | infinite} command in INTERFACE CONFIG mode. 

The lifetime parameter configures the amount of time the IPv6 host can use the IPv6 RDNSS address for name resolution. The lifetime range is  0 to 4294967295 seconds. When the maximum lifetime value, 4294967295,  or the infinite keyword is specified, the lifetime to use the RDNSS address 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.

The DNS server address does not allow the following:
  • link local addresses

  • loopback addresses

  • prefix addresses

  • multicast addresses

  • invalid host addresses

If you specify this information in the IPv6 RDNSS configuration, a DNS error is displayed.

Example for Configuring an IPv6 Recursive DNS Server

The following example configures a RDNNS server with an IPv6 address of 1000::1 and a lifetime of 1 second.
DellEMC(conf-if-te-1/1)#ipv6 nd dns-server ?
X:X:X:X::X          Recursive DNS Server's (RDNSS) IPv6 address
DellEMC(conf-if-te-1/1)#ipv6 nd dns-server 1000::1 ?
<0-4294967295>       Max lifetime (sec) which RDNSS address may be used for name resolution
infinite             Infinite lifetime (sec) which RDNSS address may be used for name resolution

DellEMC(conf-if-te-1/1)#ipv6 nd dns-server 1000::1 1
