A route gateway is usually an IP address through which the target addresses are reachable, an interface name is normally only used on point-to-point links with /32 addresses. So in your case it would be 192.168.0.x where this is the address of the router which is also connected to the 192.168.122.0/...

According to the description in the OP, folks at the ISP use the method mentioned in par. 4.1.4 of the RIPE document, i.e. they sacrifice a single /64 from the /48 they gave you as a link subnet.

Out of interest how is the provider supplying the /48?
