Monitoring MLD Proxy

To display MLD proxy parameters, use the following show commands.

show ipv6 mld-proxy

• Use to display MLD proxy parameters for a VR.
• Field descriptions

• Routing Process—MLD proxy protocol
• Administrative state—State of MLD proxy in the software
• Operational state—Operational state of MLD proxy: enabled or disabled
• total interfaces—Number of MLD proxy interfaces on the VR; currently only one upstream interface per VR
• state—Operational state of the MLD proxy interfaces: enabled or disabled
• multicast group—Number of multicast groups associated with MLD proxy interfaces

• Example

host1#show ipv6 mld-proxy

Routing Process MLD Proxy, Administrative state enabled, Operational state

enabled

    total 1 upstream interface, state enabled

    1 multicast group

show ipv6 mld-proxy groups

• Use to display information about multicast groups that MLD proxy reported.
• Field descriptions

• Grp Address—Address of the multicast group
• Interface—Type and identifier of the upstream interface associated with the multicast group
• Grp Mode

• Blank—No sources included or excluded for this group
• Include—Sources included for this group
• Exclude—Sources excluded for this group

• Count—Total number of multicast groups associated with this interface

• Example 1

host1#show ipv6 mld-proxy groups

show ipv6 mld-proxy interface

• Use to display information about the interface on which you configured MLD proxy.
• To view information about a particular interface, enter an interface type and specifier, such as atm 3/0. For details about interface types and specifiers, see JUNOSe Command Reference Guide, About This Guide.
• Specify the brief option to display a summary rather than a detailed description.
• Field descriptions

• Interface—Type of upstream interface. For details about interface types, see JUNOSe Command Reference Guide, About This Guide.
• Address—Address of upstream interface
• Administrative state—State of upstream interface in the software: enabled or disabled
• Operational state—Physical state of upstream interface: enabled or disabled
• Version—MLD version on this interface
• State—Presence of MLDv1 routers on the same subnet as this upstream interface
• Unsolicited report interval—Time interval at which this upstream interface sends unsolicited group membership report
• multicast group—Number of multicast groups associated with this upstream interface
• Interface statistics Rcvd—Statistics for messages received on this interface

• v1 queries—Number of MLDv1 multicast listener queries received
• v1 report—Number of MLDv1 multicast listener reports received
• v2 queries—Number of MLDv2 multicast listener queries received
• v2 report—Number of MLDv2 multicast listener reports received

• Interface statistics Sent—Statistics for messages sent from this interface

• v1 reports—Number of MLDv1 multicast listener reports sent
• v1 leaves—Number of multicast listener done messages sent
• v2 reports—Number of MLDv2 multicast listener reports sent

• Example 1

host1#show ipv6 mld-proxy interface

Administrative state enabled, Operational state enabled

Interface parameters:
