This page demonstrates configuring IPv6 Prefix Delegation over PPPoE in RouterOS, showing how to set up DHCPv6-PD pools on servers and clients, including interface configuration and verification of dynamic prefix delegation.

IPv6 PD over PPP

This example demonstrates how to set up PPPoE server and client to use IPv6 Prefix Delegation.

IPv6 Prefixes can be delegated over PPP interfaces. When a client connects, PPP will automatically add a dynamic DHCPv6-PD server. This allows running a DHCPv6 client on PPP interfaces.

Configuration

Server

The dhcpv6-pd-pool parameter under PPP Profiles is used to enable PPP-PD. PPP will use the specified IPv6 pool to create a dynamic DHCP server.

So the first step is to add an IPv6 pool:

/ipv6/pool
add name=myPool prefix=2001:db8:7501:ff00::/60 prefix-length=62

Now we can configure a PPP profile and add a PPPoE server

/ppp/profile/set default dhcpv6-pd-pool=myPool

/interface/pppoe-server/server 
add service-name=test interface=ether1

Client

On the client side we need to set up PPPoE client interface and run DHCP client on it.

/interface/pppoe-client
add name=client-test interface=ether1 user=a1 service-name=test

/ipv6/dhcp-client 
add interface=client-test pool-name=ppp-test pool-prefix-length=64

Testing status

On the server side check if a dynamic DHCP server is added and prefix is bound to a specific client:

[admin@RB1100] /ipv6/dhcp-server> print 
Flags: D - dynamic, X - disabled, I - invalid 
 #    NAME              INTERFACE            ADDRESS-POOL            LEASE-TIME
 0 D  <pppoe-a1>        <pppoe-a1>           myPool                  3d        

[admin@RB1100] /ipv6/dhcp-server/binding> print 
Flags: X - disabled, D - dynamic 
 #   ADDRESS                                        DU       IAID SER.. STATUS 
 1 D 2001:db8:7501:ff04::/62                                  247 <pp.. bound

On the client side, check if DHCP client is bound and pool is added:

[admin@x86-test] /ipv6/dhcp-client> print 
Flags: D - dynamic, X - disabled, I - invalid 
 #    INTERFACE           STATUS        PREFIX                            EXPIRES-AFTER  
0    client-test          bound         2001:db8:7501:ff04::/62           2d23h18m17s  

[admin@x86-test] /ipv6/pool> print 
Flags: D - dynamic 
 #   NAME                        PREFIX                                   PREFIX-LENGTH
 0 D ppp-test                    2001:db8:7501:ff04::/62                             64
