IPv6 RA scenario

In this scenario, two host computers are auto-configured with IP addresses using IPv6 RA. In addition, the switch provides the hosts with an address of a recursive DNS server. The physical topology of the network looks like this:

Procedure
  1. Configure the interfaces with IPv6 addresses. 
    switch# config
switch(config)# interface 1/1/1
switch(config-if)# ipv6 address 2001::1/64
switch(config)# interface 1/1/2
switch(config-if)# ipv6 address 2001::2/64
switch(config)# interface 1/1/3
switch(config-if)# ipv6 address 2001::3/64
  2. Enable transmission of all IPv6 RA messages. 
    switch(config-if)# no ipv6 nd suppress-ra
