Multicast - route-map on IOS-XE 16.9.4
When implementing Multicast in conjunction with Network Address Translation (NAT) on a Cisco router running IOS-XE 16.9.4, the source address translation for multicast traffic fails when applied with a Route-map.
This is Cisco bug Caveat ID number CSCwb25137 and has been resolved in all IOS-XE 17.X versions.
