no ip mroute-cache deprecated command

When implementing Multicast routing, since IOS 15, the no ip mroute-cache command is deprecated. When you try to use this, you get this error:

R1(config-if)#no ip mroute-cache 
The above command is deprecated. Use MFIB commands instead.

Instead, you should add these commands on the interface:

R1(config-if)#no ip mfib cef in
R1(config-if)#no ip mfib cef out 

And try the following debug command:

debug ip mfib ps
