WAN failover solutions

Steve Coady
Beginner

Hello

Anyone out there recommend a redundant solution?

Scenario:

I have a remote Data Center on a private 100MM AT&T AVPN link.I have a toal of (17) sites including the Data Center on the AVPN cloud

I am inquiring with other providers (Verizon (FIOS), Comcast, local communications companies) to get a redundant solution in place.

To keep costs down, I would rather not have to bring a second WAN link placed at each of my (17) remote offices.

AT&T offers an ANIRA solution wich essentially uses a Comcast or local internet provider to route traffic acorss a redundant link, which then get's tunneled back into my AT&T AVPN cloud.

My first question is "How can I use a secondary WAN provider and have them tunnel traffic back into my private network on another service provider"

POP redundancy is important so they both do not ride the same "last mile".

Anyone out there recommend a redundant solution?

Have you considered using site-site VPN or maybe DMVPN? Whichever you choose will depend on what fits your architecture. But a Comcast internet is the cheapest when deployed with VPN. I have 21 branch offices using MPLS, and I'm using IPSEC VPN as backup.

For redundancy from physical faults you may need to buy secondary WAN links. You should check with the ISP for the information of WAN services provided by them?

Make sure you do not have your Primary and Backup link from the same ISP. Buy your backups from a different one.

Steve,

Anira also supports 4g connections if you can get them in your area. I'm not sure if you're using their AVPN solution (mpls), but they can tie your internal subnets into their mpls cloud. If you fail over to the netgate, their network will have a route pointing to your netgate for internal subnets. Not the fastest solution by far, but it gets you off of a wire...

HTH,

Thank you for the reply

Last mile diversification between providers is always a must.

Thank you for the reply

I currently use the AT&T ANIRA, IPSEC VPN, for my remotes sites. Comcast provide most of the links. For my data Center, Comcast would require construction  in excess of $50k.
