Using a RouterOS to connect to POST LuxFibre


I have used a Routerboard running Mikrotik’s RouterOS to connect to a POST LuxFibre FTTH access for some time. I have been asked in the past to aid with similar setups, so here comes my configuration for the RouterOS CLI.

Note: This setup does NOT (yet) provide access to the Voice service delivered by POST.

In this example I’m using “ether1” to connect to the GPON NTU. (I haven’t yet tested the RouterBoard GPON SFP module, so no need to ask about it 🙂 )

/interface ethernet
set [ find default-name=ether1 ] comment=LuxFibre

We also need to configure VLAN 35 on this interface.

/interface vlan
add interface=ether1 name=luxfibre35 vlan-id=35

Finally we also need to configure a PPP profile and a PPPoE client to connect to the Internet. Please replace USERNAME and PASSWORD by your PPPoE username and password.

/ppp profile
add change-tcp-mss=yes name=pppoe-luxfibre use-mpls=no
/interface pppoe-client
add add-default-route=yes comment=LuxFibre default-route-distance=1 \
 disabled=no interface=luxfibre35 max-mru=1492 max-mtu=1492 \
 name=pppoe-luxfibre password=PASSWORD profile=pppoe-luxfibre \
 use-peer-dns=yes user=USERNAME

 Do not forget IPv6. 😉

/ipv6 dhcp-client
add add-default-route=yes interface=pppoe-luxfibre \
 pool-name=luxfibre-pool pool-prefix-length=48 request=prefix

This covers the external connectivity, in a later post I will cover the configuration for your internal configuration and very basic network security.
