I am not able to create a cluster peer because all the IP's are in Default IP space and if that is the case, how can i solve it.
I'd say, "No route to host" is pretty self-explanatory. You need route to remote network (and remote network needs route to local site). It can be default gateway or it can be network/host specific route, but this is standard IP connectivity, nothing specific to cluster peering or cDOT in general.

So far there is no indication it is related to IP space. You may need different IP space if different destinations with the same IP addresses are reachable via different gateways. But there is not enough information to speculate about it.
