Configuring IP Multicast Protocols

Displaying Another Multicast Router’s Multicast Configuration

The HP implementation of Mrinfo is based on the DVMRP Internet draft by T. Pusateri, but applies to PIM and not to DVMRP. To display the PIM configuration of another PIM router, use the following CLI method.

NOTE: This feature is not supported for DVMRP.

USING THE CLI

To display another PIM router’s PIM configuration, enter a command such as the following:

HP9300# mrinfo 207.95.8.1

207.95.8.1-> 207.95.8.10 [PIM/0 /1 ]

207.95.10.2-> 0.0.0.0 [PIM/0 /1 /leaf] 209.157.25.1 -> 0.0.0.0 [PIM/0 /1 /leaf] 209.157.24.1 -> 0.0.0.0 [PIM/0 /1 /leaf]

207.95.6.1-> 0.0.0.0 [PIM/0 /1 /leaf]

128.2.0.1-> 0.0.0.0 [PIM/0 /1 /leaf]

Syntax: mrinfo <ip-addr>

The <ip-addr> parameter specifies the IP address of the PIM router.

The output in this example is based on the PIM group shown in Figure 9.9 on page 9-54.The output shows the PIM interfaces configured on PIM router C (207.95.8.1). In this example, the PIM router has six PIM interfaces. One of the interfaces goes to PIM router B. The other interfaces go to leaf nodes, which are multicast end nodes attached to the router’s PIM interfaces. (For simplicity, the figure shows only one leaf node.)

When the arrow following an interface in the display points to a router address, this is the address of the next hop PIM router on that interface. In this example, PIM interface 207.95.8.1 on PIM router 207.95.8.1 is connected to PIM router 207.95.8.10. The connection can be a direct one or can take place through non-PIM routers. In this example, the PIM routers are directly connected.

When the arrow following an interface address points to zeros (0.0.0.0), the interface is not connected to a PIM router. The interface is instead connected to a leaf node.

NOTE: This display shows the PIM interface configuration information, but does not show the link states for the interfaces.

The information in brackets indicates the following:

•The multicast interface type (always PIM; this display is not supported for DVMRP)

•The Time-to-Live (TTL) for the interface.

•The metric for the interface

•Whether the interface is connected to a leaf node (“leaf” indicates a leaf node and blank indicates another PIM router)

For example, the information for the first interface listed in the display is “PIM/0 /1”. This information indicates that the interface is a PIM interface, has a TTL of 0, and a metric of 1. The interface is not a leaf node interface and thus is an interface to another PIM router.

The information for the second interface in the display is “PIM/0 /1/leaf”. This information indicates that the interface is a PIM interface, has a TTL of 0 and a metric of 1, and is connected to a leaf node.

USING THE WEB MANAGEMENT INTERFACE

You cannot display another router’s PIM configuration using the Web management interface.
