Backup DMVPN cloud.

Hi all,

I currently have a DMVPN cloud that encompasses most of about 25 North American sites. It's basically T1 connected 2651's homing back to a pair of 3745's on a DS3 connection. What I would like to do is add a DSL interface to all of my North America routers and enable a secondary (backup) cloud in case of T1 failures. Is this possible? I am willing to look at other solutions as well. (I had also given thought to homing the DSL links to s 3005 I have here as well, basically making a static connection with a high cost that would switch over if the site T1 went down.)

Thanks in advance.

Re: Backup DMVPN cloud.

tmcmurray,

This is absoultely possible. I am doing this at our company. I put together a document on "exactly" how to configure the hub and spoke routers. We also have a T-1 to each spoke with DSL attached to the 2nd ethernet interface for backup for when/if the T-1 goes down. DMVPN is a great technology for doing exactly what you want to accomplish. Send me your email and I'll send you the document.

Regards,

Brandon
