hi

i try it today again just for one interface in this case.

on host a:
inet 10.90.5.202 255.255.255.0 10.90.1.255 \
        carpdev em4 \
        group management_if \
        carpnodes 91:0,101:100

on host  b:

inet 10.90.5.202 255.255.255.0 10.90.1.255 \
        group management_if \
        carpdev em4 \
        carpnodes 101:0,91:100

this works !

i can see the traffic on both interfaces and boxes.

now i try to change the next carp interface
on host a:
inet 10.90.1.202 255.255.255.0 10.90.1.255 \
        group management_if \
        carpnodes 90:0,100:100


after the setup on the first box  my whole network go's down.

my question is can i do carp loadblanacing on a multiple carp box ( 5 carp
interfaces ) ?

is this the right way to do lb carp like i ahead described ?
