Hi to all!
I have a trouble with simultaneity of switching between carp interfaces.
FreeBSD 12.0
My config for host A:
ifconfig_vlan2_alias0="inet vhid 1 advskew 100 pass password alias
192.168.2.10/32"
ifconfig_vlan3_alias0="inet vhid 2 advskew 100 pass password alias
192.168.3.10/32"
ifconfig_vlan4_alias0="inet vhid 3 advskew 100 pass password alias
192.168.4.10/32"
ifconfig_vlan5_alias0="inet vhid 4 advskew 100 pass password alias
192.168.5.10/32"
ifconfig_vlan6_alias0="inet vhid 5 advskew 100 pass password alias
192.168.6.10/32"
ifconfig_vlan7_alias0="inet vhid 6 advskew 100 pass password alias
192.168.7.10/24"
ifconfig_vlan8_alias0="inet vhid 7 advskew 100 pass password alias
192.168.8.10/30"
ifconfig_vlan9_alias0="inet vhid 8 advskew 100 pass password alias
192.168.9.10/30"
For host B the same, but advskew = 1.
Hosts are routers and work correctly, when all carp interface have
master status at the same host. But if I try to get this state only by
carp tools, this work good, when one of my hosts have
net.inet.carp.demotion = 0
But this not always like this. For example, after turning on host A have
demotion = 1920 and host B = 1440. And in this situation I usually have
something like this:
# ifconfig | grep carp
carp: MASTER vhid 1 advbase 1 advskew 100
carp: BACKUP vhid 2 advbase 1 advskew 100
carp: BACKUP vhid 3 advbase 1 advskew 100
carp: BACKUP vhid 4 advbase 1 advskew 100
carp: BACKUP vhid 5 advbase 1 advskew 100
carp: BACKUP vhid 6 advbase 1 advskew 100
carp: BACKUP vhid 7 advbase 1 advskew 100
carp: BACKUP vhid 8 advbase 1 advskew 100
I tried to set vhid = 1 for all carp interfaces, but with the same result.
Of cource, net.inet.carp.preempt = 1 for both hosts.
Started from FreeBSD 10, I used script to set the carp value based on
the value of one of the interfaces, but not sure, that it is right
decision. May be someone can suggest me what's wrong?
