RE: Multicast Troubleshooting

I found it:

R1#deb ip mfib pak
MFIB IPv4 pak debugging enabled for default IPv4 table
R1#
*Sep 26 17:35:49.843: MFIBv4(0x0): Pkt (10.0.0.1,239.1.2.3) from
FastEthernet0/0 (TS) accepted for forwarding
*Sep 26 17:35:49.847: MFIBv4(0x0): Pkt (10.0.0.1,239.1.2.3) from
FastEthernet0/0 (TS) sent on FastEthernet0/1
R1#

Info about the new "debug ip mfib" commands here:

Subject: Multicast Troubleshooting

Hello group,

I was troubleshooting a multicast issue and I found that our old "no ip
mroute-cache" and "debug ip mpacket" combination does not work anymore:

R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#
R2(config)#int f0/0
R2(config-if)#
R2(config-if)#
R2(config-if)#no ip mroute-cache
The above command is going to be deprecated. Use MFIB commands instead.
R2(config-if)#
R2(config-if)#
R2(config-if)#do sh ver | inc IOS
Cisco IOS Software, 7200 Software (C7200-ADVENTERPRISEK9-M), Version
15.0(1)M7, RELEASE SOFTWARE (fc2)
R2(config-if)#
R2(config-if)#

It seems the "ip mroute-cache" command was deprecated starting from 15.0(1)M
and 12.2(33)SRE:

I used some of the mfib commands like "no ip mfib cef input" and "no ip mfib
cef output" but I don't get anything, I mean, the debug ip mpacket doesn't
show anything. I'm sure there's a way to get back the old behavior.

If someone knows the new procedure please share with the group.

Thanks.
