# Enable MFIB route debugging for the public network. When PIM-DM is enabled on interfaces,
output similar to the following example is generated:
<Sysname> debugging mfib route
*Nov 12 17:43:01:491 2007 Sysname MFIB/7/MFIB ROUTE:
(public net):Receive no cache report,add dummy entry (3.4.5.6, 226.1.1.1)(A07109)
*Nov 12 17:43:01:492 2007 Sysname MFIB/7/MFIB ROUTE:
(public net):Entry (3.4.5.6, 226.1.1.1) is added to dummy list(A063866)
*Nov 12 17:43:01:492 2007 Sysname MFIB/7/MFIB ROUTE:
(public net):The Dummy entry (3.4.5.6, 226.1.1.1) is added(A061861)
// The control plane received a multicast packet (3.4.5.6, 226.1.1.1). No forwarding entry for
the packet was found. The control plane created a dummy entry for it.
*Nov 12 17:43:01:492 2007 Sysname DP_MFIB/7/ROUTE:
(IPv4 0): (3.4.5.6, 226.1.1.1) Add entry successfully! (D44157)
// The data plane also created an entry for the multicast packet (3.4.5.6, 226.1.1.1).
*Nov 12 17:43:01:495 2007 Sysname MFIB/7/MFIB ROUTE:
(public net):Receive add-entry message of entry (3.4.5.6, 226.1.1.1) from MRM, OIF
num is 1.(A112135)
// An add-entry message was received from the MRM for adding an entry for (3.4.5.6,
226.1.1.1) with the outgoing interface number of 1.
*Nov 12 17:43:01:495 2007 Sysname DP_MFIB/7/ROUTE:
(IPv4 0): (3.4.5.6, 226.1.1.1) Delete entry successfully! (D44246)
*Nov 12 17:43:01:496 2007 Sysname DP_MFIB/7/ROUTE:
(IPv4 0): (3.4.5.6, 226.1.1.1) Add entry successfully! (D44157)
*Nov 12 17:43:01:496 2007 Sysname MFIB/7/MFIB ROUTE:
(public net):Entry (3.4.5.6, 226.1.1.1) is deleted from dummy list(A063908)
*Nov 12 17:43:01:497 2007 Sysname MFIB/7/MFIB ROUTE:
(public net):The dummy entry (3.4.5.6, 226.1.1.1) is replaced by actual entry(A07407)
*Nov 12 17:43:01:497 2007 Sysname MFIB/7/MFIB ROUTE:
(public net):The entry (3.4.5.6, 226.1.1.1) is added(A0669)
// The MFIB deleted the dummy entry for (3.4.5.6, 226.1.1.1) from the data plane table and
created a forwarding entry for (3.4.5.6, 226.1.1.1).

On single-core devices:
# Enable MFIB driver debugging for the public network. When PIM-DM is enabled on interfaces,
output similar to the following example is generated:
<Sysname> debugging mfib driver
*Apr 26 12:53:18:967 2000 Sysname MFIB/7/MFIB DRIVER:
(public net):Succeed to set IPMC 0x0 on interface Vlan-interface20(A082415)
// Multicast routing was enabled on VLAN-interface 20.
*Apr 26 12:53:18:979 2000 Sysname MFIB/7/MFIB DRIVER:
(public net):Succeed to set unknown packet to CPU 0x3 on interface
Vlan-interface20(A082520)
// VLAN-interface 20 was configured to send unknown data packets to the CPU.
