CR00011490
MLD,
MLD Snooping
2 The following issues occurred:
■ an MLDv2 Report message parsing issue meant that sometimes the router or
switch recognised only the first multicast group address in the message.
■ if the robustness, qinterval or qrinterval were changed, groups’ initial
timeout period was sometimes set to 260 instead of being calculated by using
the following formula from RFC 3810:
robustness * qinterval + qrinterval
■ the Other Querier Timeout—the timeout period for registration of the “All
Router” group—was not calculated by using the following formula from
RFC 3810:
robustness * qinterval + qrinterval/2
■ When robustness, qinterval or qrinterval were set to non-default values,
the timeout values (or MA timers) of newly reported multicast address groups
were not updated to reflect these changed values.
■ MLD & MLD Snooping groups were sometimes incorrectly set with a timer
value that was inconsistent with the internally maintained individual port
timers. Therefore, registered groups could lose port members temporarily.
These issues have been resolved. This CR also included enhancements to MLD
and MLD Snooping; see “Enhancements to MLD and MLD Snooping
(CR00011490)” on page 65.

PIM 6 2 Occasionally, PIM6 Sparse Mode did not elect the router or switch as the BSR
when no other PIM neighbour was present.
This issue has been resolved. When no other BSR candidates are present, the
router or switch correctly becomes the BSR.
