  • 1.  HP E5406zl PIM Sparse Mode no longer adding addresses to multicast routing table.

    Hi All,

     

    Stuck on a really anoying problem.  We have configured Multicast routing for the first time 2 weeks ago using PIM-SM on a stand alone E5406zl configured with static routing between approx 10 vlans.  We had the configuration working but as of this morning the sh ip mroute command is not showing any learning multicast routes at all. Here is the relevant configuration commands:

     

    ip multicast routing 
router pim 
    enable 
    bsr-candidate 
    bsr-candidate source-ip-vlan 11 
    rp-candidate 
    rp-candidate source-ip-vlan 11 
    rp-candidate group-prefix 224.0.0.0 240.0.0.0 
    rp-candidate hold-time 150 
    state-refresh 45 
exit
vlan 10-200
    ip pim-sparse 
        ip-addr any 
    exit 
exit

     

    The output from sh ip igmp groups shows the following:

     I can see that the address we are interested in (239.0.208.0) is in the igmp list accross multiple vlans but for some reason the switch is not adding it to the multicast routing table. 

     

    I have tried all the obvious commands to try and find the problem but am completely stuck now.  The switch is the E-BSR.

     

    Any suggestions on how to find out what process the switch is going through to decide when/why to add an address to the multicast routing table? 

     

    Thanks
