Hi

Try setting the advskew to a number greater than 200 and less then 254. This seems to be the most stable.

For best practice our primary runs with carp and pfsync values of '1'. And the backup runs with carp and pfsync values of '2'.

We do this for two reasons.

1) it is extremely stable!

2) We found that CARP master is almost random/unstable when both firewalls have the same value (esp '0'), because;

"When advbase is set to 0 the skew value alone is used to calculate how often advertisements are sent (the advertisement window) using this formula:
Window in microseconds = advskew * 1000000 / 256

E.g. 100 * 1000000 / 256 = 390625us

So it would take much to cause a flip..

Setting advbase to 1 on both is better as this is more stable if you want to have the same carp demote counters..

Good luck :)

That shows me what they are supposed to be.

That does not show me what they actually are.

ifconfig output will show what they actually are.
