Suppressing the advertisement of all configured IPv6 addresses

By default, prefix information in router advertisement (RA) messages includes IPv6 addresses configured on the interface. The following task suppresses the advertisement of all configured IPv6 addresses in RA messages for an interface.
  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 suppress-ra address command with the all keyword to suppress all IPv6 addresses configured on the interface in RA messages. 
    device(config-if-e1000-1/1/3)# ipv6 nd suppress-ra address all

The following example suppresses all IPv6 addresses configured on the interface in RA messages. 

device# configure terminal
device(config)# interface ethernet 1/1/3
device(config-if-e1000-1/1/3)# ipv6 nd suppress-ra address all
