show multicast route
Syntax
show multicast route <brief | detail | extensive | summary> <active | all | inactive> <group group> <inet | inet6> <instance instance name> <logical-system (all | logical-system-name)> <oif-count> <regular-expression> <source-prefix source-prefix>
Syntax (EX Series Switch and the QFX Series)
show multicast route <brief | detail | extensive | summary> <active | all | inactive> <group group> <inet | inet6> <instance instance name> <regular-expression> <source-prefix source-prefix>
Description
Display the entries in the IP multicast forwarding table. You can display
similar information with the show route table inet.1 command.
On all SRX Series Firewalls, when a multicast route is not available, pending sessions are not torn down, and subsequent packets are queued. If no multicast route resolve comes back, then the traffic flow has to wait for the pending session to timed out. Then packets can trigger new pending session create and route resolve.
Options
| none | Display standard information about all entries in the multicast forwarding table for all routing instances. |
| brief | detail | extensive | summary | (Optional) Display the specified level of output. |
| active | all | inactive | (Optional) Display all active entries, all entries, or all inactive entries, respectively, in the multicast forwarding table. |
| group group | (Optional) Display the cache entries for a particular group. |
| inet | inet6 | (Optional) Display multicast forwarding table entries for IPv4 or IPv6 family addresses, respectively. |
| instance instance-name | (Optional) Display entries in the multicast forwarding table for a specific multicast instance. |
| logical-system (all | logical-system-name) | (Optional) Perform this operation on all logical systems or on a particular logical system. |
| oif-count | (Optional) Display a count of outgoing interfaces rather than listing them. |
| regular-expression | (Optional) Display information about the multicast forwarding table entries that match a UNIX OS-style regular expression. |
| source-prefix source-prefix | (Optional) Display the cache entries for a particular source prefix. |

Output Fields
Table 1 describes the output
fields for the show multicast route command. Output fields are listed in the approximate
order in which they appear.
Field Name |
Field Description |
Level of Output |
||
|---|---|---|---|---|
Instance |
Name of the routing instance. |
|
||
family |
IPv4 address family ( |
All levels |
||
Group |
Group address. For any-source multicast routes, for example for bidirectional PIM, the group address includes the prefix length. |
All levels |
||
Source |
Prefix and length of the source as it is in the multicast forwarding table. |
All levels |
||
Incoming interface list |
List of interfaces that accept incoming traffic. Only shown for routes that do not use strict RPF-based forwarding, for example for bidirectional PIM. |
All levels |
||
Upstream interface |
Name of the interface on which the packet with this source prefix is expected to arrive. |
All levels |
||
Upstream rpf interface list |
When multicast-only fast reroute (MoFRR) is enabled, a PIM router propagates join messages on two upstream RPF interfaces to receive multicast traffic on both links for the same join request. |
All levels |
||
Downstream interface list |
List of interface names to which the packet with this source prefix is forwarded.
|
All levels |
||
Number of outgoing interfaces |
Total number of outgoing interfaces for each (S,G) entry. |
|
||
Session description |
Name of the multicast session. |
|
||
Statistics |
Rate at which packets are being forwarded for this source and group entry (in KBps and pps), and
number of packets that have been forwarded to this prefix. If
one or more of the kilobytes per second packet forwarding
statistic queries fails or times out, the statistics field
displays Note:
On QFX Series switches and OCX Series switches, this field does not report valid statistics. EX4300 Series switches don’t report valid multicast statistics. |
|
||
Next-hop ID |
Next-hop identifier of the prefix. The identifier is returned
by the routing device’s Packet Forwarding Engine and is also displayed in the output
of the |
|
||
Incoming interface list ID |
For bidirectional PIM, incoming interface list identifier. Identifiers for interfaces that accept incoming traffic. Only shown for routes that do not use strict RPF-based forwarding, for example for bidirectional PIM. |
|
||
Upstream protocol |
The protocol that maintains the active multicast forwarding route for this group or source. When the |
|
||
Route type |
Type of multicast route. Values can be (S,G) or (*,G). |
|
||
Route state |
Whether the group is |
|
||
Route count |
Number of multicast routes. |
|
||
Forwarding state |
Whether the prefix is pruned or forwarding. |
|
||
Cache lifetime/timeout |
Number of seconds until the prefix is removed from the
multicast forwarding table. A value of |
|
||
Wrong incoming interface notifications |
Number of times that the upstream interface was not available. |
|
||
Uptime |
Time since the creation of a multicast route. |
|
||
Sensor ID |
Sensor ID corresponding to multicast route. |
|
