Hi all:

My two servers have carp configured and work fine. but the pings directed to the virtual interface (carp interface for both server) result duplicated replies:

64 bytes from icmp_seq=0 ttl=64 time=0.049 ms
64 bytes from icmp_seq=1 ttl=64 time=0.016 ms (DUP!)
64 bytes from icmp_seq=2 ttl=64 time=0.020 ms
64 bytes from icmp_seq=3 ttl=64 time=0.035 ms (DUP!)
64 bytes from icmp_seq=4 ttl=64 time=0.016 ms
64 bytes from icmp_seq=5 ttl=64 time=0.015 ms (DUP!)
64 bytes from icmp_seq=6 ttl=64 time=0.014 ms
64 bytes from icmp_seq=7 ttl=64 time=0.014 ms (DUP!)

Is that normal? VRRP virtual interface don't seem to behave that way.
