laser designation system on Flankers

and Fulcrum and eventually on Mig-25 AG variants ?

especially for Flankers / Fulcrum : does they have external pods or internal laser designation system ?
I’m not sure but I think internal for Su-32/34 but for the others ????

For Mig-25 there is a bomb version but I don’t know yet if they can be guided or just unguided .
