Bug ID: 210481
Summary: [Carp] do not work correctly advertisement skew in the
case of several vhid on a single physical interface
Product: Base System
Version: 10.3-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: freebsd-bugs@FreeBSD.org
Reporter: ad...@support.od.ua
Hello.
I have two almost identical router server - bras1 and bras2.
FreeBSD 10.3-STABLE # 0: Wed Jun 22 07:33:13 EEST 2016
They planned to create more than a hundred vlan interface. As a backup and
balancing traffic plan to use CARP.
It is also planned to use the PF NAT and pfsync for synchronization NAT
sessions.
I do not work correctly advertisement skew in the case of several vhid on a
single physical interface.

sysctl:

It r297791, but upgrade to r302074 not help :(
Change net.inet.carp.preempt from 0 to 1 or vice versa, too, especially not
affect the behavior of the CARP.
As a temporary measure to help the team, introduced to bras1:
ifconfig lagg1.800 vhid 2 state backup
ifconfig lagg0.1224 vhid 3 state master
At the same time in the next pair of servers (r273154) advskew works correctly.
