You will have to understand the MBGP address families. One of the basic rule of MBGP is that when I'm advertising a route from a specific address family, the next hop has to be from the same address family. So, you will have to make sure the next hop is from the same address family. Couple of examples for you: A basic rule of mBGP is that when advertising a route from a specific Address-family the next-hop address has to be from the same address-family, or you will have to use roue-maps.
