Re: Need provider suggestions - BGP transit over GRE tunnel

My network spans a multicity geographic area using microwave radio
links. The point of the GRE tunnel is to allow me to establish a BGP
session to another AS using a consumer grade Internet connection
(cheap) over the public Internet. I don't want to build out additional
microwave paths to a new datacenter to become multihomed.

I have read your email a few times and i dont see how this makes sense.

Why do you need a public AS and PI space? Your gre tunnel wont need it or be
able to use it. A gre tunnel is just a replacement for a physical pipe.

If your datacenter based presence goes down, you will need a pipe at your
office, or some other location speaking bgp that can annouce your block
anyway.

Currently we have redundant (router and physical path) links to a
single AS where we get our transit, and speak BGP to them using a
private ASN. This configuration has not been meeting our reliability
requirements, so we will be getting our own ASN from ARIN, and moving
from PA to PI IP space.

Our new provider will be used for backup purposes only. We would like
to minimize the monthly cost of this connection; to do this, we are
planning to use a VZ business FIOS connection with symmetrical
bandwidth to establish a GRE tunnel to a datacenter somewhere, and
bring up a BGP session over that tunnel. I'd like to know if there are
providers that offer such a service on a regular basis, and if so, if
anyone is doing this and has words of wisdom.

Thanks in advance.
