https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=269908 --- Comment #11 from Zhenlei Huang <zlei@FreeBSD.org> --- While testing carp, I see multiple issues. The fix will not come immediately, so I'd like to propose you do the following to see if it helps. 1. While in the example of the man doc, host A and B are set different advskew, I recommend against and set advskew to a same one. So you can change vhid state on either host. 2. The preferred way to make a host master or backup is `ifconfig nic0 vhid 1 state master` or `ifconfig nic0 vhid 1 state backup`. 3. For aliases, the recommend prefixlen / netmask is 32 / 255.255.255.255 4. If `CISCO ACI endpoint table messed up`, can you try setting only virtual IP 10.10.4.19 on both hosts and see whether it helps or not ? i.e., only `ifconfig nic0 vhid 1 advskew 20 10.10.4.19/28`. Apparently the fourth suggestion has drawbacks and you lost the ability to reach exact host via host IP (not the virtual one). -- You are receiving this mail because: You are the assignee for the bug.
