This example show how to display information related to a specific multicast route. In the output below,
the arrow in the margin points to information about a partical short cut:
Router# show ip mroute 239.1.1.2 4.4.4.4
IP Multicast Routing Table
Flags:D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
L - Local, P - Pruned, R - RP-bit set, F - Register flag,
T - SPT-bit set, J - Join SPT, M - MSDP created entry,
X - Proxy Join Timer Running, A - Candidate for MSDP Advertisement,
U - URD, I - Received Source Specific Host Report, Z - Multicast Tunnel
Y - Joined MDT-data group, y - Sending to MDT-data group
Outgoing interface flags:H - Hardware switched
Timers:Uptime/Expires
Interface state:Interface, Next-Hop or VCD, State/Mode
(4.4.4.4, 239.1.1.2), 1d02h/00:03:20, flags:FTZ
Incoming interface:Loopback0, RPF nbr 0.0.0.0, Partial-SC
Outgoing interface list:
Vlan10, Forward/Sparse-Dense, 1d02h/00:02:39 (ttl-threshold 5)
This example shows how to display the entries for a specific multicast group address:
Router# show mls ip multicast group 230.31.31.1
Multicast hardware switched flows:
(*, 230.31.31.1) Incoming interface:Vlan611, Packets switched:1778
Hardware switched outgoing interfaces:Vlan131 Vlan151 Vlan415 Gi4/16 Vlan611
RPF-MFD installed
This example shows how to display PIM group to active rendezvous points mappings:
Router# show mls ip multicast rp-mapping
State:H - Hardware Switched, I - Install Pending, D - Delete Pending, Z - Zombie
RP Address State RPF DF-count GM-count
60.0.0.60 H Vl611 4 1
This example shows how to display information based on the group/mask ranges in the RP mapping
cache:
Router# show mls ip multicast rp-mapping gm-cache
State:H - Hardware Switched, I - Install Pending, D - Delete Pending,
Z - Zombie
RP Address State Group Mask State Packet/Byte-count
60.0.0.60 H 230.31.0.0 255.255.0.0 H 100/6400
This example shows how to display information about specific MLS IP multicasting groups:
Router# show mls ip multicast rp-mapping df-cache
State:H - Hardware Switched, I - Install Pending, D - Delete Pending, Z - Zombie
RP Address State DF State
60.0.0.60 H Vl131 H
60.0.0.60 H Vl151 H
