Subject: [rbak-nsp] Clips and multicast problem
Message-ID: <>
Content-Type: text/plain; charset=us-ascii


We distribute multicast using clips authorization.
Last days we have problem with random subscribers losing access to some 
multicast groups.

Only way I found to fix it, is to restart:
process restart IGMP

Part of config we using:

We bind it:

 dot1q pvc 2009
  description EVIOSTB0
  bind interface eviostream0 evio
  service clips dhcp context evio

And context:

 ip nat pool ip_evio_lan1_nat napt multibind
  address port-block 1 to 15

 interface evstb0 multibind
  ip address

 interface eviostream0
  ip address
  pim sparse-mode passive

 nat policy ip_evio_lan1_nat_policy
! Default class
  inbound-refresh udp
! Named classes
  access-group NATACL
   class NAT
    pool ip_evio_lan1_nat evio
    timeout tcp 6000
    endpoint-independent filtering udp
    inbound-refresh udp
   class NATLESS
    inbound-refresh udp

 subscriber default
   ip multicast send permit
   ip multicast receive permit
   ip igmp service-profile IPTV1
   port-limit 1
 igmp service-profile IPTV1
  priority 10

from my observation it looks like when some subscribers is 
deauthenticated/disconnected he also prevent others from using multicast group
which he been using. 
Currently running SEOS-

Any hints ?
