This information is in relation to our Etherway/Etherflow services.
==IP settings==
PPP or PPPoE is not used on Ethernet services. Instead a direct IP interlink subnet between A&A routers and the customer's router.
The Ethernet link provides a connection between your network and ours, and we connect your network to the internet. To achieve this we provide IP addresses on the link. A block of IP addresses is used specifically to link between us, and then additional addresses are provided as needed for your network.
==IPv4 interlink==
We provide a block of 8 IPv4 addresses (a /29). As usual the first and last are not usable (network and broadcast) leaving 6 usable addresses. 3 of these are for our use and 3 are usable by you.
For example, if you've been assigned 192.0.2.0/29
{| class="wikitable"
!Example IP || Use description
| 0 || Unusable▼
|-
▲| 192.0.2.0 || Unusable
|-
| 192.0.2.1 || Default Gateway for the customer to use
| 2 || A router address▼
|-
|
|-
▲| 192.0.2.3 || A&A router "B" internal address
| 4 || For your use▼
|-

| 7 || Broadcast▼
▲| 192.0.2.7 || Broadcast
|}
==IPv6 interlink==
For IPv6 we will allocate two addresses, one for each of our routers and announce these as router addresses. You should configure your firewall/router to configure its IPv6 external address automatically. If we shut down a router for maintenance it will announce itself as the low priority router before shutting down so as to ensure you switch to the other router automatically.
For example, if you've been assigned 2001:8b0:1628:4000/64
{| class="wikitable"
▲|
!Example IP || Use description
|-
|2001:8b0:1628:4000::1 || Default Gateway for the customer to use
|-
|2001:8b0:1628:4000::2 || A&A router
|-
|2001:8b0:1628:4000::3 || A&A router
|-
|2001:8b0:1628:4000::4 || Customer router (for example)
|}
You can set DNS manually to 2001:8b0::2020 and 2001:8b0::2021.
==Dual routers and VRRP==
==Additional IP blocks==
If you have additional IP requirements, these will be set up on your control pages and you can change the target address if you need. We will set these up to route to your gateway address initially, assuming (for IPv4) that you are using the last usable address as your firewall/router.
==DSL Fallback==
Customers with an Ethernet circuit can also have one or more DSL circuits, and the IP block(s) can be configured to fall back to DSL in the case of the Ethernet going down.
As well as using ADSL or FTTC circuits for Fallback, it can also be done by using one of our 3G or 4G data SIMs, or our L2TP service.
Usually this can be setup by staff.

==BGP==
==Multiple links==
If you have multiple independent etherflows then these appear on separate VLANs at your end. The above applies to each etherflow to us for internet access. Etherflows to other sites you may have are entirely for you to configure as you wish at an Ethernet level.
