DHCPv6 relay scenario 1

In this scenario, DHCP relay on the server enables two hosts to obtain their IP addresses from a DHCP server on a different subnet. The physical topology of the network looks like this:

Procedure
  1. Enable DHCP relay. 
    switch# config
switch(config)# dhcpv6-relay
  2. Define an IPv6 helper address on interfaces 1/1/1 and 1/1/2 . 
    switch(config)# interface 1/1/1
switch(config-if)# ipv6 address 2002::22/64
switch(config-if)# ipv6 helper-address 2001::1
switch(config-if)# interface 1/1/2
switch(config-if)# ipv6 address 2002::21/64
switch(config-if)# ipv6 helper-address 2001::1
switch(config-if)# quit
  3. Verify DHCP relay configuration. 
    switch# show dhcpv6-relay
  DHCPv6 Relay Agent : Enabled
  Option 79          : Disabled
    switch# show ipv6 helper-address

 Interface: 1/1/1
 IPv6 Helper Address                            Egress Port
 ---------------------------------------------- -----------
 2001::1                                        1/1/3

 Interface: 1/1/2
 IPv6 Helper Address                            Egress Port
 --------------------------------------------   -----------
 2001::1                                        1/1/3
