30.10. Common Address Redundancy Protocol (CARP) doc

[Chris Hunnewell]

I was recently working with this document and having issues getting CARP working.  I identified one of the issues as one of my own creation.  I was working with these settings on a VMware vSphere and by default this doesn't allow promiscuous mode.  I was wondering if the document should be updated to show this as a requirement of CARP.  The second problem I was having I noted during the boot of the server.  I had the following line in the rc.conf file:

ifconfig_vmx0_alias0="vhid 1 advskew 100 pass redacted alias 155.247.167.127/32"

This is close to the example given in the documentation outside of adjusting for my network card and settings.  During the boot I would get the following error:

/etc/rc: WARNING: $ifconfig_vmx0_alias0 needs leading "inet" keyword for an IPv4 address.

I changing the line to this:

ifconfig_vmx0_alias0="inet vhid 1 advskew 100 pass redacted alias 155.247.167.127/32"

After changing the line I did not note any errors during the boot of the OS.  I'm running a fully patched version of 10.2.  I did find this is similar to how a virtual host would be configured in the rc.conf file but find nothing about this for CARP.  Does this need to be updated in the document or is there some other issue?

Thanks,
