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
