Equinix Internet Access - additional IPs

Hi team,

When ordering Internet Access over fabric for a redundant connection type, how many sets of additional IPs are provided?

For example is it just one set of additional IPs anywhere between /30 to /24?

Or as it's a redundant pair do we get two sets of additional IPs e.g. 

additional IP range 1:

anything from /30 to /24

additional IP range 2:

anything from /30 to /24

Thanks

That is correct @chana. The /29 will be part of a larger aggregate we advertise to our upstream internet peers. The prepending you do to influence inbound traffic to your edge devices will only be applicable within the Equinix network.

Hi @chana great question! We checked in with the EIA team, Here's what they shared:

Only one set is provided; here's a link to the documentation on it. 

In the image below, the lower green circle represents an additional subnet that the customer will get, ranging from /30 to /24, depending on your choice. 

The team is working on a feature that would allow you to get more than one subnet. 

Hopefully, this helps provide more guidance!

    Hi Shannon,

    Thanks for confirming! In that case would we be able to take a /29 and subnet this into smaller networks?

    Our use case for wanting two separate networks is so that we can apply AS path prepending to them to influence inbound traffic even if it's only applicable within the Equinix network. For example here is what we are looking to achieve -

    Equinix PA IP 88.36.66.0/29

    Subnetted and advertised out like so:

    circuit 1

    88.36.66.6/30 - prepend

    88.36.66.1/30 – no prepend

    circuit 2

    88.36.66.1/30 - prepend

    88.36.66.6/30 – no prepend

    Thanks

    Hello​, @chana, yes, you can take a larger prefix, split it up and advertise the smaller blocks via BGP just like you have in your example. As you deduce, it is only applicable within the  EIA network.

      Hi, @rcarrara, just want to check if we were to subnet as above then the individual IPs would still be reachable publicly, it's just prepending that's only applicable within Equinix network, is that correct? 

      Thanks
