MPLS Option C | ASBR not exchanging label?

Hi, Would like to ask if announcing routes using network command from BGP affect the output of the mpls label? Because tried using the redistribute from IGP into BGP and the label works, not sure if this is just in GNS3 bug or something... though seen that there are method that they are using the Network command in BGP.
