- Update to version 4.2
Major bug fix and feature release. Support for static routes and
improved configuration support for IGMP.
Changes
* Support for controlling IGMP Last Member Query Count using
the igmp-robustness setting in mrouted.conf, default 2.
* Support for tuning the IGMP Last Member Query Interval using
a new setting igmp-query-last-member-interval <1-1024>.
* Support for static multicast routing (*,G), similar to SMCRoute
* New phyint static-group GROUP setting in mrouted.conf
* multiplestatements supported, but no ranges (yet).
* Proper tracking of lower-version host members (IGMP), when a
lower version host is detected for a group, a timer is set
according to RFC3376, and while in this compat mode
higher-version IGMP is not allowed to change state. E.g., in
IGMPv1 compat, IGMPv2 LEAVE is * ignored for the group,
similar to the phyint being in igmpv1 mode.
* Allow IGMP reports from source address 0.0.0.0, required as
per RFC3376, sec. 4.2.13, not supported until now. This
should greatly improve interop with IGMP snooping switches and
DHCP clients that have not yet received a lease
* Improved support for running mroutectl under watch(1). No more
artifacts due to unknown ANSI escape sequences to probe width
* Delayed PID file creation until after initial startup delay,
there is nobody home until after that delay, so no point in
announcing availability until after that
Fixes
*IGMPv3 membership reports were parsed incorrectly.
The problem affects users that use source specific multicast
join, i.e., (S,G) join/leave using IGMPv3. Support for
