==Application Examples==
===Use received prefix for local RA===
Consider following setup:
[[File:DHCP-PD-local-RA.png]]
* DHCP client on router R2 receives delegated /64 prefix from the DHCP server (R1).
* Router R2 uses received prefix to set up RA on the local interface
Detailed print should show status of the client and we can verify if prefix is received
[admin@x86-test] /ipv6 dhcp-client> print detail
Flags: D - dynamic, X - disabled, I - invalid
0 interface=bypass pool-name="test-ipv6" pool-prefix-length=64 status=bound
prefix=2001:db8:7501:ff04::/62 expires-after=2d23h11m53s
Notice that server gave us prefix 2a02:610:7501:ff04::/62 . And it should be also added to ipv6 pools
[admin@MikroTik] /ipv6 pool> print
Flags: D - dynamic
# NAME PREFIX PREFIX-LENGTH
0 D test-ipv6 2001:db8:7501:ff04::/62 64
It works!
Now you can use this pool, for example, for pppoe clients.
