Dual ISP 877 is this going to work?

I have setup a 877 with Adv IP as follows but I can't test till I get to site so not sure if this will work.

ADSL - ISP1

VLAN2 - Linked FE3 - ISP2

VLAN1 - Internal

I have created PBR for NAT.

I have an IP SLA track to mark the routes.

I've done this before on 1800s I think this is OK but I need to create a VPN tunnel that will switch interfaces in the event the main VLAN2 goes down. This is the bit i'm not 100% I can do.

I've attached the config.

They've changed the CBAC and ACL to this new Zones method and it confusing me a bit.

yes, Dual ISP is possible on 877 routers. If you are using backup connection then make sure to configure routing.

Using a VPN that is tied to a physical interface which is one of your ISP uplinks is likely to fall down if that ISP uplink is down.
