Pinging multicast address

    Hi everyone.

     

    I am trying to generate Multicast stream by using ping on SRX,  on Cisco we just specify the address say 235.1.1.1 and we see pings ggo out but on SRX ( and EX 4200)  I see this is not the case.  Is there some specific knob needed to be configured?

     

    Thanks and have a nice weekend!!

    Yes there is a knob.

     

    Try something like:

    ping 225.1.1.1 bypass-routing interface fe-1/2/10.0 ttl 10 count 1000000000

     

    Regards, Wojtek

    The command mentioned by colleague will only be applicable to SRX with 11.1 junos onwards..

    you should be able to ping multicast ip using the command as long as you can configure SAP in edit protocols hierarchy.

    However, EX4200 doesn't support this:

    {master:0}[edit]
    root@ex4200# show protocols sap
    ##
    ## Warning: configuration block ignored: unsupported platform (ex4200-24f)
    ##
    listen 225.100.100.100;

    {master:0}[edit]
    root@ex4200#

    I see that 11.4R11 on SRX100 have this:

    root# show protocols sap
    listen 255.100.100.100;

    [edit]
    root# run show version
    Model: srx100b
    JUNOS Software Release [11.4R11.4]
    ..
    So you may configure your mcast ip in sap and use multicast ping for testing
