How-to use CARP?

[Stephane Raimbault]

Hi all,

I'm having a bit of a problem running 5.4-RELEASE and carp.  All the  
documentation that I read (man carp and other web based sources)  
indicate to simply create my carp interface as follows:

ifconfig carp0 create

However when I run this... I get the following error:

# ifconfig carp0 create
ifconfig: SIOCIFCREATE: Invalid argument
#


Any thoughts or comments that can steer me in the right direction  
would be appreciated.


I'm sure I'm missing something obvious... here's my dmesg.boot
