I am not sure if I understood what you are actually asking.
The rulesets “Check host with PING” and “Check current routing” are both active checks. In general, each active check rule generates one check item on each host it is applied to. So, if you want to apply the rule twice on the same host, you need to create two rules with different parameters.
An active check is always executed on the Checkmk site where the host is monitored. If you want to ping/traceroute the same host from different Checkmk sites, you need to create the host object multiple times on each Checkmk site.
I hope this helps.
Edit: it looks like the traceroute check has no option to alter the service description. So there can only one check per host, and the service description is always “Routing”. I sent a bug report to the feedback mail address. For now, you can create two host objects if you need both IPv4 and IPv6 traceroutes.
