Displaying the multicast configuration for another multicast router
The command example above indicates that the source address 10.157.24.62 is three hops (three
PIM switches) away from PIM Switch A. In PIM terms, each of the three switches has a forwarding
state for the specified source address and multicast group. The value following “Thresh” in some
of the lines indicates the TTL threshold. The threshold 0 means that all multicast packets are
forwarded on the interface. If an administrator has set the TTL threshold to a higher value, only
packets whose TTL is higher than the threshold are forwarded on the interface. The threshold is
listed only for the PIM switch hops between the source and destination.
Displaying the multicast configuration for another multicast router
The Brocade implementation of Mrinfo is based on the Internet draft by T. Pusateri, but applies to
PIM. To display the PIM configuration of another PIM router, use the following CLI method.
To display another PIM router PIM configuration, enter a command such as the following.
TurboIron#mrinfo 10.95.8.1
10.95.8.1 -> 10.95.8.10 [PIM/0 /1]
10.95.10.2 -> 0.0.0.0 [PIM/0 /1 /leaf]
10.157.25.1 -> 0.0.0.0 [PIM/0 /1 /leaf]
10.157.24.1 -> 0.0.0.0 [PIM/0 /1 /leaf]
10.95.6.1 -> 0.0.0.0 [PIM/0 /1 /leaf]
10.2.0.1 -> 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
output shows the PIM interfaces configured on PIM router C (10.95.8.1). 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 10.95.8.1 on PIM router
10.95.8.1 is connected to PIM router 10.95.8.10. 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.
