We have 2mb mpls network between three sites. Each site also has its own internet connection for hosting webserver and internal users to access internet. Each site has a few internal subnets. Each site currently has a 2800 series ISR.
Goal / Proposed:
1) Increase Internet connection to 10mbps and configure site-to-site VPNS in a mesh
configuration so that each site has a vpn to each other site. This would create six vpn tunnels.
2) Configure so that only Exchange and VoiP traffic use the MPLS network under normal conditions.
All other traffic (backup/misc apps) should be routed to use the Internet VPNs. If the MPLS fails
of course we would like the Exchange and VoiP traffic to fail over to the VPN connections as well
until the MPLS comes back up. This is where I need help with what features to configure.
In regards to Question 1: Does this seem fairly common? Any gotchas/feedback?
In regards to Question 2: How would I configure this? What features/configurations, etc.?
As much detail as possible would be appreciated and I can research from there.
