I'm trying to find a solution for the following setup, 
Blue ISP is the primary.
Both are MPLS connection only.
the requirement is,
if Blue ISP @ site A/B/C or HQ fails, it should automatically switch to Red ISP 2 in site A AND HQ until Blue IPS connection is restored. The trouble is on certain sites, the second device is non-cisco, so BGP - HSRP is out of question, what next ?.
Many thanks.
