              P_stable: is true if the default router is expected to be stable network data
              P_default: is true if border router offers the default route for P_Prefix
              P_slaac_preferred: is true if Thread device is allowed auto-configure address using P_Prefix
              P_Dhcp: is true if border router is a DHCPv6 Agent
              P_preference: is two-bit signed integer indicating router preference
              P_on_mesh: is true if P_Prefix is considered to be on-mesh
              P_nd_dns: is true if border router is able to supply DNS information obtained via ND
  
          Returns:
              True: successful to configure the border router with a given prefix entry
              False: fail to configure the border router with a given prefix entry
