Redistribution VPN site to site subent into OSPF

Dear community,

we need to redistribure the vpn subnet into OSPF.

We have an ospf neiborghip on XG V18 MR4 to a core router, all the network connected on the XG are correctly adverstised to core router, now we need to adverstised the VPN site to site subents of the XG into the OSPF. 

Is there any chance to do it?

Thank you
