IP SLA incorporating L2 vlans

[SharpNetSol]

Hi

I'm a Cisco novice looking at how to provide an automatic failover solution for a primrary fibre link with a secondary VSAT connection. I have been looking at IP SLA which looks straightforward, however the data being sent over the fibre has been seperated into two layer 2 vlans. Is it possible to incorporate layer 2 vlans into an IP SLA setup?

The hardware in question are Cisco 2811 routers running IOS version 12.3(8)T7

Bear in mind that IP SLA is dealing with IP which operates at layer 3. A VLAN operates at layer 2 and I do not know of any way to have IP SLA process a layer 2 operation.

But perhaps the VLAN has an interface vlan x? This would provide a layer 3 interface for that VLAN and would route traffic for the VLAN. In that case IP SLA could examine reachability of the vlan interface and indirectly process for the layer 2 VLAN.

The VLANs are phyically configured on FE ports on a switching module but with no ip address sadly.

Is there any other methodology of providing failover for layer 2 VLANs?
