Configuring backup WAN interface

Hi,

I want to configure a backup interface to an Internet-facing interface that is connected to our Main site via a DMVPN. I was thinking that I would configure the backup interface exactly like the Primary-Active interface and allow it to bring up a DMVPN with the Main site when the Primary interface fails or the ISP service fails.

What are the things involved in accomplishing this?

Should I configure an IPSLA that is tracking the Primary interface??

If so, does anyone have a good doc for this?

Thank you, Pat.

Hi,

Have a look at this doc written by Marwan for use of SLA tracking with multiple providers.
