I'm setting up a second router that's going to sit next to an existing one and become a redundant failover system. The current one is in production, and I've been converting some of the existing LAN subnets on it to use carp interfaces and making them primary and the new box secondary. I also set up a carp interface on the WAN side and made the new box primary for testing as that didn't exist before. That all worked fine when I set it up by hand, but when I rebooted the new box, the old box stayed primary for everything including the WAN interface, which I tracked down to the carp demote counter, which ended up at 2 on the new box after the reboot:
bash-4.3# ifconfig -g carp carp: carp demote count 2 After I manually decreased the demote counter by 2 back to 0 the WAN interface master switched back to the new box. I'm not sure what's doing that at boot? I am running ospfd on the box, but I don't have any demote statements in my configuration. I'm also running npppd, but I don't see anything about that and carp demotion. What else might be setting carp demotion values? Thanks...
