Can I query multicast route table via SNMP?

  • 1.  Can I query multicast route table via SNMP?

    Posted 11-02-2015 05:40

    I would like to use SNMP to query an MX960 running JUNOS 12.3 to list what Multicast groups are being announced and what interface they are being announced from.  Subsequently I would like to do the same on a receiving MX960 to find out what Multicast groups are being joined and by what interface.  Also, my interfaces are participating in Routing-instances.

     

    I want to use an snmpwalk command from a Solaris UNIX workstation to gather the information.  Does anyone know what OID I could use to query the Multicast Route Table of a specific Routing-instance on an MX960 running JUNOS 12.3 and match the Multicast-Group to interface?

     

    Thanks,

     

    Greg

    This was the OID I was looking for.  Thanks!

     

    I still had to figure out how to query the route table pertaining to a specific routing-instance and the solution is to reference the routing-instance as part of the community string as follows:

     

    snmpwalk -v <version> -c <routing-instance>@<community> <hostname/IP> <OID>

    The key is to put the routing-instance name before the community string separated by the "@" sign.

     

    Example:  snmpwalk -v 2c -c iptv@public 10.100.100.1 1.3.6.1.3.60.1.1.2

    I also found OIDs relating to IGMP and PIM.

    Searching the Juniper MIB explorer I think this may be the tree you are looking for.
