[pfSense-discussion] lagg + carp: carp not sending multicast via lagg interface

[Fabio C Flores]

Hello there, I know lagg is not yet supported but since its freebsd Im encouraged to use it. After creating the interface using ifconfig lagg0 create it works nicely and I can setup everything under the web gui including firewall rules. My setup requires the use of CARP on the lagg interface which Im failing to make it work. The lagg itself is failing over as expected, but looks like its not sending multicast link events via the lagg. I've checked it with tcpdump. I found this fix http://www.freebsd.org/cgi/query-pr.cgi?pr=113956 , which would sort the problem. Im not sure if 1.2-RC4, the version Im using, incorporates that fix. This is causing both master and backup nodes to become MASTER: master > carp1: flags=49<UP,LOOPBACK,RUNNING> mtu 1500 >       inet 10.0.2.3 netmask 0xffff0000 >       carp: MASTER vhid 12 advbase 1 advskew 0 backup > carp1: flags=49<UP,LOOPBACK,RUNNING> mtu 1500 >        inet 10.0.2.3 netmask 0xffff0000 >        carp: MASTER vhid 12 advbase 1 advskew 100 This is how I created the lagg interface under config.xml: >               <shellcmd>ifconfig lagg0 create</shellcmd> >               <shellcmd>ifconfig lagg0 laggproto failover laggport em0 laggport bge1 10.0.2.7 netmask 255.255.0.0</shellcmd> >               <shellcmd>route delete 10/16</shellcmd> >               <shellcmd>route add -net 10/16 -interface lagg0</shellcmd> Thanks in advance, Fabioc
