This object reports a route target value used in the router's MPLS Layer-3 VPN route-target distribution policy, which controls which VPN routes get imported into or exported from a given VRF (Virtual Routing and Forwarding instance). The MIB's own description is terse, but an administrator would read this to verify which route targets are governing route leaking for a particular VRF when troubleshooting why routes are or aren't appearing across VPN sites. For example, this object might hold a value like "65000:100", the standard ASN:number format used to identify a specific route target in BGP/MPLS VPNs.
