Description Neil Horman 2011-06-23 19:35:50 UTC 
Description of problem:
Current RHEL6 kernel has no support for bridge based igmp snooping.  Without this feature, multicast frames may not be received properly, leading to ipv6 errors, such as not generating SLAAC based ipv6 global addresses

Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
1.configure a bridge br0
2.attach a physical interface to it that emits router advertisements
3.bring br0 up
  
Actual results:
no SLAAC ipv6 address generated

Expected results:
SLAAC ipv6 global address assigned to br0 based on router advert.

Additional info:
This is fixed upstream with the addition of these patches:
