router_address Specifies the unicast IP address of the router for which you want information.
from_address Specifies the unicast IP address of the interface where the mrinfo request is generated.
seconds Specifies a maximum time to wait for a response. The range is 1–30 seconds.
multi_resp_timeout Specifies a maximum time to wait for additional responses after the first response is received. The range is 0 to 3 seconds.
vrname Specifies a VR name.

from_address: IP address of interface from which the mrinfo query is generated.

timeout: 3 seconds

multiple-response-timeout: 1 second

vr: DefaultVR

Usage Guidelines

The last column of the mrinfo command output displays information in the following format:

[Metric/threshold/type/flags]

This information is described in detail in the Syntax Description..

Table 1. mrinfo Command Display Data
Data Description
Metric This should always be 1 because mrinfo queries the directly connected interfaces of a device.
Threshold This should always be 0 because the threshold feature is not supported in ExtremeXOS software.
Type The type specifies the multicast protocol type. Because the ExtremeXOS software only supports PIM, this value is always pim.
querier The querier flag indicates that the queried router is the IGMP querier.
leaf The leaf flag indicates that the IP interface has no neighbor router.
down The down flag indicates that the interface link status is down.

Example

The following command requests information from multicast router 1.1.1.1:

Switch.1 # mrinfo 1.1.1.1
1.1.1.1 [Flags:PGM]
2.2.2.1 -> 2.2.2.2 [1/0/pim/querier]
1.1.1.1 -> 0.0.0.0 [1/0/pim/querier/leaf]
8.8.8.1 -> 8.8.8.4 [1/0/pim/querier]
3.3.3.1 -> 0.0.0.0 [1/0/pim/down]

This command was first available in ExtremeXOS 12.4.
