Description

Display Layer 2 multicast routing information (with IGMP snooping) for destination ports on satellite devices.

This command lists multicast routing entries by route prefix and bridge domain name (Junos Fusion Provider Edge). Each route entry lists the next-hop ID (NH Index) used when the aggregation device performs ingress multicast replication. When local replication is enabled and the VLAN has multicast destination extended ports on a satellite device, the aggregation device:

Creates a satellite device next-hop chain to those multicast destinations through their corresponding satellite device.
Updates the multicast route entry with a link to the satellite next-hop chain (Linked NH Index).

If a multicast route does not have a satellite next-hop chain, Linked NH Index is 0. When the Linked NH Index value is non-zero, NH Index refers to the original next-hop information, but the aggregation device uses the satellite next-hop chain (Linked NH Index) for routing multicast traffic to satellite device extended ports. Use the detail or extensive option to expand the output to include details about the original next-hop and satellite next-hop chains.

Options

brief \| detail \| extensive	(Optional) Display the specified level of output. The default output level is `brief`. The `detail` output level expands the original and satellite device next-hop chains for each route displayed. The `extensive` output level includes details about multicast next-hop entry update events used mainly for troubleshooting.
bridge-domain-name `bridge-domain-name`	(Junos Fusion Provider Edge only) Filter output to display bridge domain flooding information only for the specified bridge domain name.
group `group-address`	Filter output to display flooding information only for the specified multicast group.
source `source-address`	Filter output to display flooding information only for the specified multicast source.
vswitch-name `virtual-switch-name`	Filter output to display flooding information only for the specified Layer 2 virtual switch.

Output Fields

Table 1 lists the output fields for the show multicast snooping route satellite command. Output fields are listed in the approximate order in which they appear.

Table 1: show multicast snooping route satellite Command Output Fields
Field Name	Field Description	Level of Output
`Route`	Multicast route information listed by route prefix under this heading.	All
`(S, G/m)`	Multicast entry state.	All
`Bridge Domain`	Bridge domain or VLAN name.	All
`NH Index`	Multicast next-hop ID (original multicast next hop used with ingress multicast replication).	brief
`Linked NH Index`	Multicast satellite next-hop ID (next hop used with egress multicast replication).	brief
`Next-hop information`	Detailed list of next-hop chain information for the original and satellite next-hop chains, listed by original next-hop index (`NH Index`) and satellite next-hop chain index (`Linked NH Index`) output field values.	detail extensive
`Mrouter`	Next-hop chain list for multicast routers connected to the bridge domain or VLAN.	detail extensive
`aggregation-device`	Next-hop IDs and corresponding interfaces for the composite next hop to reach local multicast destination ports on the aggregation device.	detail extensive
`satellite-device-id id`	Satellite device ID with the next-hop IDs and corresponding interface names for the composite next-hop chain to reach extended ports that are multicast destinations on that satellite device. When an ECID has been assigned to destination extended ports on a satellite device, this field lists the satellite next-hop ID, the corresponding virtual satellite device interface (`sd-fpc-id/0/0`), and the allocated ECID (`label` field).	detail extensive
`AE`	Link aggregation group interface next-hop IDs and interface names multicast destination composite next hops.	detail extensive
`label`	ECID associated with one or more multicast destination extended ports on the satellite device in the `satellite-device-id` field.
`When`	Elapsed time since an event related to a multicast next-hop entry addition or update.	extensive
`Event`	Brief description of the event related to a multicast next-hop entry addition or update.	extensive
`Action`	Brief description of actions that resulted from the event.	extensive
