Entries for prefixes that are in the access list look like you would expect and those PIM joins succeed. So what exactly does "rump always-replicate" do? Am I right that it's basically only allowing the prefixes in the ACL to be used for multicast RPF?
Sounds plausable. XR and IOS works differently when it comes to RPF for multicast. This command could be workaround for that.
Proper way (at least it was in XR 3.6 - 3.8 time) is to put multicast sources into BGP address-family multicast. By default, if the source is only in BGP af-unicast then it's not considered valid for multicast RPF check in XR.
