Which two statements about the device that generated the output are true?

Explanation: In this example we can see that the s, T, and I flags are set. Here is a list of the
flags and their meanings:
show ip mroute Field Descriptions
Field
Description
Flags:
Provides information about the entry.
D – Dense
Entry is operating in dense mode.
S – Sparse
Entry is operating in sparse mode.
B – Bidir Group
Indicates that a multicast group is operating in bidirectional mode.
s – SSM Group
Indicates that a multicast group is within the SSM range of IP addresses. This flag is reset if
the SSM range changes.
C – Connected
A member of the multicast group is present on the directly connected interface.
L – Local
The router itself is a member of the multicast group.
P – Pruned
Route has been pruned. The Cisco IOS software keeps this information so that a downstream
member can join the source.
R – RP-bit set
Indicates that the (S, G) entry is pointing toward the RP. This is typically prune state along the
shared tree for a particular source.
F – Register flag
Indicates that the software is registering for a multicast source.
T – SPT-bit set
Indicates that packets have been received on the shortest path source tree.
J – Join SPT
For (*, G) entries, indicates that the rate of traffic flowing down the shared tree is exceeding the
SPT-Threshold set for the group. (The default SPT-Threshold setting is 0 kbps.) When the J- Join
shortest path tree (SPT) flag is set, the next (S, G) packet received down the shared tree triggers
an (S, G) join in the direction of the source, thereby causing the router to join the source tree.
For (S, G) entries, indicates that the entry was created because the SPT-Threshold for the group
was exceeded. When the J- Join SPT flag is set for (S, G) entries, the router monitors the traffic
rate on the source tree and attempts to switch back to the shared tree for this source if the traffic
rate on the source tree falls below the SPT-Threshold of the group for more than 1 minute.
M – MSDP created entry
Indicates that a (*, G) entry was learned through a Multicast Source Discovery Protocol (MSDP)
peer. This flag is only applicable for a rendezvous point (RP) running MSDP.
X – Proxy Join Timer Running
Indicates that the proxy join timer is running. This flag is only set for (S, G) entries of an RP or
“turnaround” router. A “turnaround” router is located at the intersection of a shared path (*, G) tree
and the shortest path from the source to the RP.
A – Advertised via MSDP
Indicates that an (S, G) entry was advertised through an MSDP peer. This flag is only applicable
for an RP running MSDP.
U – URD
Indicates that a URD channel subscription report was received for the (S, G) entry.
I – Received Source Specific Host Report
Indicates that an (S, G) entry was created by an (S, G) report. This (S, G) report could have
been created by IGMPv3, URD, or IGMP v3lite. This flag is only set on the designated router
(DR).
