I have a pair network gateway boxes running FreeBSD 11 and pf. Upstream runs VRRP to provide redundant links, one to each gateway. Internally I'm using CARP for failover.
All works well, but I find that manually failing over the link is a bit complicated. In short I have this: em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 media: Ethernet autoselect (100baseTX <full-duplex>) status: active carp: BACKUP vhid 1 advbase 1 advskew 50 igb0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 media: Ethernet autoselect (1000baseT <full-duplex>) status: active carp: BACKUP vhid 2 advbase 1 advskew 50 igb0.2: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 status: active vlan: 2 vlanpcp: 0 parent interface: igb0 carp: BACKUP vhid 3 advbase 1 advskew 50 groups: vlan That's two internal vlans and one external network. Each interface has its own vhid since that's the advice I had in the past. Now, what command can I type that I could run remotely (SSH over the em0 link) to force all the CARP addresses simultaneously to decrease the advskew and become MASTER. Alternatively I could run something on the MASTER to make it BACKUP. Everything I've done so far is one command per interface which has got me in trouble before as I manage to accidentally remove my own access to the box before I'm done.
