Hello
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 178.214.23.65/32 port-block 1 to 15
!
interface evstb0 multibind
ip address 192.168.30.1/26
!
interface eviostream0
ip address 172.16.0.1/24
pim sparse-mode passive
!
nat policy ip_evio_lan1_nat_policy
! Default class
ignore
inbound-refresh udp
icmp-notification
! Named classes
access-group NATACL
class NAT
pool ip_evio_lan1_nat evio
timeout tcp 6000
endpoint-independent filtering udp
inbound-refresh udp
icmp-notification
class NATLESS
ignore
inbound-refresh udp
icmp-notification
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-12.1.1.12
Any hints ?
