Re: One /22 Two ISP no BGP

The problem we have now is that we got our /22 from arin to do multihoming.
If we dump tlb, no more multihoming? No /22. Is that correct?

We also have a contract with tlb.
$$$ 1.5yrs left...

Just got final confirmation from ISP1 that they will not do BGP with us.

ISP1 is Telebec.

My subnet

What can we do now ? Any suggestions ?

Do you know who is upstream of ISP2? We've established that Telebec is
only connected to Bell Canada. If ISP2 also has a connection to Bell
then you don't gain anything with Telebec except this huge mess and
horrible hacks to work around their lack of BGP.

Also, VTL peers with Sprint and SAVVIS. Based on this information I'd
just drop Telebec completely. They only have one upstream. You won't get
any redundancy with them since they're just giving you a connection to
Bell, which VTL already gives you. Here's the view from my SAVVIS router
with Sprint as the preferred path:
