Multicast problem

Hello community.

I have a problem with multicast on my Juniper MX80 router. It works, but sometimes all of group drops and I see errors in log.

 

 

Jul  7 03:17:00  newage bbe=smgd[1622]: SMGD_SOFT_ERR: soft-err: ../../../../../src/junos/usr.sbin/bbe-svcs/smd/plugins/mcast/bbe_mcast_plugin.c: 6011: bbe_mcast_cleanup_mc_af()

Configuration of IGMP:

show protocols igmp     

query-interval 125;
query-response-interval 10;
query-last-member-interval 1;
interface xe-0/0/3.3 {
    version 2;
    promiscuous-mode;
    group-policy packet_five;
}

 

 

I have no idea how can I resolve that issue.

Did JTAC give you a PR number that the bug was covered under?

 

Typically this type of behavior will be a software bug.  These are tracked by Juniper as PR (problem reports) each given a number and then a specific version of Junos has the fix that that particular bug.  

 

So if JTAC has identified the bug affecting your traffic and saying you need to upgrade to a specific version of Junos this is where that but is fixed.  Ask them for the PR number and bug description if you are not sure the upgrade will fix the issue.

 

the public version of the PR database is here.

I didn't find PR in problem report tracker, how can I report that issue to tracker?

REports from customers are taken via JTAC tickets.  You open a support case and they determine if the behaviour is a known bug or a new one and then track it through the process to the final fix.

I have tried to start ticket, but my company doesn't has Technical Support.

Maybe someone from community could help me.
