show pim mdt data-mdt-joins

Syntax

Description

In a draft-rosen Layer 3 multicast virtual private network (MVPN) configured with service provider tunnels, display the advertisements of new multicast distribution tree (MDT) group addresses cached by the provider edge (PE) routers in the specified VPN routing and forwarding (VRF) instance that is configured to use the Protocol Independent Multicast (PIM) protocol.

Options

instance `instance-name`	Display data MDT join packets cached by PE routers in a specific PIM instance.
logical-system (all \| `logical-system-name`)	(Optional) Perform this operation on all logical systems or on a particular logical system. Note: Draft-rosen multicast VPNs are not supported in a logical system environment even though the configuration statements can be configured under the logical-systems hierarchy.

Output Fields

Table 1 describes the output fields for the show pim mdt data-mdt-joins command. Output fields are listed in the approximate order in which they appear.

Table 1: show pim mdt data-mdt-joins Output Fields
Field Name	Field Description
C-Group	IPv4 group address in the address space of the customer’s VPN-specific PIM-enabled routing instance of the multicast traffic destination. This 32-bit value is carried in the C-group field of the MDT join TLV packet.
C-Source	IPv4 address in the address space of the customer’s VPN-specific PIM-enabled routing instance of the multicast traffic source. This 32-bit value is carried in the C-source field of the MDT join TLV packet.
P-Group	IPv4 group address in the service provider’s address space of the new data MDT that the PE router will use to encapsulate the VPN multicast traffic flow (C-Source, C-Group). This 32-bit value is carried in the P-group field of the MDT join TLV packet.
P-Source	IPv4 address of the PE router.
Timeout	Timeout, in seconds, remaining for this cache entry. When the cache entry is created, this field is set to 180 seconds. After an entry times out, the PE router deletes the entry from its cache and prunes itself off the data MDT.
