Load balance between MPLS and VPN

[yangfrank]

Dear All

There are two locations, site A and site B. I am confused with it. Any one can help to understand it? The site A and B are connected with two paths. One is MPLS and another is VPN over internet. we want MPLS as primary path and L2L VPN as backup. Only when primary path is down, VPN can be used. How can we configure it ? Can you give me suggestion ? or a link. Thank you.

Hello yangfrank,

You can set this with a floating static using tracking with ip sla.

Your primary route will be via MPLS

ip route 0.0.0.0 0.0.0.0 x.x.x.x track 1 (via MPLS)

ip route 0.0.0.0 0.0.0.0 y.y.y.y 10 (via VPN)

ip sla 1

icmp-echo z.z.z.z source interface gix/x (MPLS interface)

ip sla schedule 1 life forever start-time now

track 1 ip sla 1 reachability

here are examples:

Hello.

Could you share your configuration?

If you have more than 1 router per site, could you share network diagram?
