Description
Requests information from a multicast router.
Syntax Description
| 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. |
Default
router_address: One of the local interface addresses.
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..
| 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]
History
This command was first available in ExtremeXOS 12.4.
