Hello, I have a CCR2004-16G-2S+ that, if I enable IGMP snooping in the bridge, reboots with the error "kernel failure in previous boot." Has anyone ever encountered something similar? If I don't enable IGMP snooping, everything works perfectly.
I've seen similar reports but it obviously also depends on which ROS version you are using and that little piece of important info, you did not reveal.
So, what version does this happen with ?
Did you try downgrade / upgrade to other version ?
Since when did this start ?
I solved it. Before, the router was doing something completely different. So, this scenario was configured yesterday and it immediately gave me the problem. Today I solved it.
I'll explain how:
When IGMP Snooping is enabled on the bridge, the "Multicast Router" parameter is set to "Temporary Query" by default.
If I set this parameter to "Permanent," everything works fine and there is no reboot with a log “kernel failure in previous boot”
BEFORE
/interface bridge
add igmp-snooping=yes mtu=1500 multicast-router=temporary-query name=bridge1
AFTER
/interface bridge
add igmp-snooping=yes mtu=1500 multicast-router=permanent name=bridge1
The updated version is 7.20.7 Long Term
