Hello,
This should be possible. I do have 7.2 systems which have lagg0 on em0/em1
VLANs over lagg0 and carp over those VLANs. So I guess carp over lagg0 should no be a problem.
lagg0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:30:48:c8:2f:50
media: Ethernet autoselect
status: active
laggproto lacp
laggport: em1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
laggport: em0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
vlan4: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=3<RXCSUM,TXCSUM>
ether 00:30:48:c8:2f:50
inet 10.62.4.253 netmask 0xffffff00 broadcast 10.62.4.255
media: Ethernet autoselect
status: active
vlan: 4 parent interface: lagg0
carp4: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500
inet 10.62.4.1 netmask 0xffffff00
carp: MASTER vhid 4 advbase 1 advskew 0
