>Number: 524
>Category: bin
>Synopsis: mrouted won't accept prunes from another fbsd mrouter
>Confidential: no
>Severity: serious
>Priority: medium
>Responsible: freebsd-bugs (FreeBSD bugs mailing list)
>State: open
>Class: sw-bug
>Submitter-Id: current-users
>Arrival-Date: Fri Jun 16 07:50:00 1995
>Originator: Soochon Radee
>Organization:
MITRE
>Release: FreeBSD 2.0-BUILT-19950616
>Environment:
Any system with the the recent multicast 3.5 port.
>Description:
Mrouted reads the prune timer from prune packets wrongly and will flood the
tunnel or link with multicast packets even after prunes are issued.
>How-To-Repeat:
Set up mrouted on any FreeBSD box so that it is upstream of another mrouter that
supports pruning. Fire up mrouted on both.
>Fix:
