Configuring DNSSL

Domain Name System Search List (DNSSL) allows IPv6 devices to advertise domain names of DNS suffixes to IPv6 hosts in a local area network. The following task configures two domain names to be advertised for an Ethernet interface, and sets separate lifetime multiplier values for each of the domain names configured.
  1. Enter the configure terminal command to access global configuration mode. 
    device# configure terminal
  2. Enter the interface command and specify an interface. 
    device(config)# interface ethernet 1/1/3
  3. Enter the ipv6 nd ra-domain-name command, specifying a domain name, to advertise the domain name in router advertisement (RA) messages. Use the lifetime-multiplier keyword, entering a value, to specify the value of the maximum RA interval. 
    device(config-if-e1000-1/1/3)# ipv6 nd ra-domain-name abc.net lifetime-multiplier 1
  4. Enter the ipv6 nd ra-domain-name command, specifying a domain name, to advertise the domain name in RA messages. Use the lifetime-multiplier keyword, entering a value, to specify the value of the maximum RA interval. 
    device(config-if-e1000-1/1/3)# ipv6 nd ra-domain-name xyz.com lifetime-multiplier 2

The following example configures the domain name of a DNS suffix as "abc.net" and sets a lifetime multiplier value of 1 for an Ethernet interface. It also configures the domain name of a DNS suffix as "xyz.com" and sets a lifetime multiplier value of 2 for the Ethernet interface. 

device# configure terminal
device(config)# interface ethernet 1/1/3
device(config-if-e1000-1/1/3)# ipv6 nd ra-domain-name abc.net lifetime-multiplier 1 
device(config-if-e1000-1/1/3)# ipv6 nd ra-domain-name xyz.com lifetime-multiplier 2
