Description

This command displays relevant multicast information from the target multicast router. Information displayed includes adjacency information, protocol, metrics, thresholds, and flags from the target multicast router. This information can be used by network operators to determine whether bidirectional adjacencies exist.

Parameters

ip-address

Specifies the IP address of the multicast capable target router.

Values

ip-address ipv4 unicast address (a.b.c.d)

dns-name

Specifies the DNS name, up to 63 characters.

router-instance

Specifies the router instance.

Default

router-name - "Base" | "management" Default - Base

service-name

Specifies the service name, up to 64 characters

Output

The following output is an example of multicast information, and Table: Output fields: mrinfo describes the output fields.

Description

This command traces the multicast path from a source to a receiver by passing a trace query hop-by-hop along the reverse path from the receiver to the source. At each hop, information such as the hop address, routing error conditions, and packet statistics are gathered and returned to the requester. A network administrator can determine where multicast flows stop and verify the flow of the multicast stream.

Parameters

source ip-address

Specifies the IP address of the multicast-capable source. This is a unicast address of the beginning of the path to be traced.

dns-name

Specifies the DNS name, up to 63 characters.

Values

ip-address ipv4 unicast address (a.b.c.d)

group ip-address

Specifies the multicast address.

destination ip-address

Specifies the IP address of the unicast destination. If this parameter is omitted, the IP address of the system where the command is entered is used. The destination parameter can also be used to specify a local interface address as the destination address to send the trace query.

Default

The default address for the destination address is the incoming IETF format for that (S,G)

hop

Specifies the maximum number of hops that will be traced from the receiver back toward the source.

Values

1 to 255

Default

32 hops (infinity for the DVMRP routing protocol).

router-instance

Specifies the router name or service ID used to identify the router instance.

Default

router-name - "Base" | "management" Default - Base

service-name

Specifies the service name, up to 64 characters.

wait-time

Specifies the number of seconds to wait for the response.

Values

1 to 60

Default

10

Output
