Displaying the multicast configuration for another multicast router
Displaying the multicast configuration for
another multicast router
The Brocade 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 commands.
NOTE
This feature is not supported for DVMRP.
To display another PIM router PIM configuration, enter a command such as the following.
Brocade#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 174 on page 1532. 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 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 in 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.
