The provider and the customer could both use HSRP (or VRRP or GLBP). It
needs a L2 connection between the two sites though, and that might not
be optimal. It can work fine though. We currently use this as a customer

The top link (between ISP PE 1 and PE 2) is not strictly necessary and
the ISP might prefer not having it.
