This object lists the name(s) of the VPN Service Provider virtual router(s) that this VRF instance can peer with, with multiple names separated by spaces when several providers are configured for redundancy. It matters operationally because the VRF automatically fails over to another listed provider if its currently selected provider's connectivity goes down, though it only peers with one provider at a time. For example, an administrator might configure this field with two provider VR names so that if the primary provider link fails, the VRF instance automatically switches to the backup.
