http://arstechnica.com/security/2014/03/hackers-hijack-300000-plus-wireless… Is there any valid reason not to black hole those /32s on the back bone? -- Sent from my Android phone with K-9 Mail. Please excuse my brevity.

ISP inbound failover without BGP
by Eric A Louie 04 Mar '14

04 Mar '14

This may sound like dumb question, but... I'm used to asking those. Here's the scenario Another ISP, say AT&T, is the primary ISP for a customer. Customer has publicly accessible servers in their office, using the AT&T address space. I am the customer's secondary ISP. Now, if AT&T link fails, I can provide the customer outbound Internet access fairly easily. So they can surf and get to the Internet. What about the publicly accessible servers that have AT&T addresses, though? One thought I had was having them use Dynamic DNS service. Are there any other solutions, short of using BGP multihoming and having them try to get their own ASN and IPv4 /24 block? It looks like a few router manufacturers have devices that might work, but it looks like a short DNS TTL (or Dynamic DNS) needs to be set so when the primary ISP fails, the secondary ISP address is advertised.

AS path not optimal
by ku po 04 Mar '14

04 Mar '14

One of my client has peering with nlayer and a provider from Asia. It seems from one major ISP in US, the best path is through this Asia provider, instead of through nlayer which we want it to be. It seems this major ISP does not have a direct peering with nlayer AS 4436 is the cause of this problem. What is the best way to address this problem?

Have them look at radware linkproof which is designed for small shops that don't want to do bgp and getting their own ASN and pi address space. Been around since 1999. http://www.radware.com/Products/LinkProof/ Hank On Mar 4, 2014 3:11 AM, Eric A Louie <elouie(a)yahoo.com> wrote: > > This may sound like dumb question, but...

Thanks to all that replied. Specially Eric @ Luma Optics. We've reached the cut off date for day. We're working on fixing the DSLAM we have on hand for use. I appreciate all the replies.

Bonus points if you tell us what continent/timezone you need this in. Getting said device to 60 Hudson and to Nowhere Island, Tahiti are 2 very different things...
