Note Multicast route byte and packet statistics are supported only for the first 1024 multicast routes. Output
interface statistics are not maintained.
Displaying IP MFIB
You can display all routes in the MFIB, including routes that might not exist directly in the upper-layer
routing protocol database but that are used to accelerate fast switching. These routes appear in the MFIB,
even if dense-mode forwarding is in use.
To display various MFIB routing routes, enter one of these commands:
The following is sample output from the show ip mfib command:
IP Multicast Forwarding Information Base
Entry Flags: C - Directly Connected, S - Signal,
IC - Internal Copy
Interface Flags: A - Accept, F - Forward, S - Signal,
NP - Not platform switched
Packets: Fast/Partial/Slow Bytes: Fast/Partial/Slow:
(171.69.10.13, 224.0.1.40), flags (IC)
Packets: 2292/2292/0, Bytes: 518803/0/518803
Vlan7 (A)
Command Purpose
Switch# show ip mfib
Displays the (S,G) and (*,G) routes that are used for packet
forwarding. Displays counts for fast, slow, and partially
switched packets for every multicast route.
Switch# show ip mfib all
Displays all routes in the MFIB, including routes that may
not exist directly in the upper-layer routing protocol
database, but that are used to accelerate fast switching.
These routes include the (S/M,224/4) routes.
Switch# show ip mfib log [n]
Displays a log of the most recent n MFIB-related events,
the most recent first.
n represents the number of events.
