Hi Ivan I could not get the manual loop prevention thing working as whenever I tried to set any tag while redistributing mp-ibgp to OSPF and then match the same on other PE while importing into OSPF it did not work. I was not able to see any tag being set.
However I have found a fix for this solution by increasing the OSPF protocol preference value to higher than BGP on the PEs under the ROuting-Instance.
