Macvlan can now optionally support forwarding between its ports, if they are in "bridge" mode. This adds support for this option to "ip link add", "ip link set" and "ip -d link show". The default mode in the kernel is now "vepa" mode, meaning "virtual ethernet port aggregator". This mode is used together with the "hairpin" mode of an ethernet bridge that the parent of the macvlan device is connected to. All frames still get sent out to the external interface, but the adjacent bridge is able to send them back on the same wire in hairpin mode, so the macvlan ports are able to see each other, which the bridge can be configured to monitor and control traffic between all macvlan instances. Multicast traffic coming in from the external interface is checked for the source MAC address and only delivered to ports that have not yet seen it. In bridge mode, macvlan will send all multicast traffic to other interfaces that are also in bridge mode but not to those in vepa mode, which get them on the way back from the hairpin. The third supported mode is "private", which prevents communication between macvlans even if the adjacent bridge is in hairpin mode. This behavior is closer to the original implementation of macvlan but stricly maintains isolation. Signed-off-by: Arnd Bergmann <arnd@arndb.de> |

Primary site is: http://developer.osdl.org/dev/iproute2 Original FTP site is: ftp://ftp.inr.ac.ru/ip-routing/ How to compile this. -------------------- 1. Look at start of Makefile and set correct values for: KERNEL_INCLUDE should point to correct linux kernel include directory. Default (/usr/src/linux/include) is right as rule. arpd needs to have the db4 development libraries. For debian users this is the package with a name like libdb4.x-dev. DBM_INCLUDE points to the directory with db_185.h which is the include file used by arpd to get to the old format Berkely database routines. Often this is in the db-devel package. 2. make The makefile will automatically build a file Config which contains whether or not ATM is available, etc. 3. To make documentation, cd to doc/ directory , then look at start of Makefile and set correct values for PAGESIZE=a4 , ie: a4 , letter ... (string) PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric) and make there. It assumes, that latex, dvips and psnup are in your path. Stephen Hemminger shemminger@osdl.org Alexey Kuznetsov kuznet@ms2.inr.ac.ru
