This my config:
...
vrrp_instance VI_WWW {
state MASTER
interface vlan102
track_interface {
vlan35
}
lvs_sync_daemon_inteface vlan34
mcast_src_ip 192.168.34.3
garp_master_delay 3
virtual_router_id 51
priority 150
# advert_int 1
# authentication {
# auth_type PASS
# auth_pass example
# }
virtual_ipaddress {
172.16.11.4/24 <---- VIP
}
debug 0
# smtp_alert
}
...
This is my output:
lbcnode1:/etc/keepalived # ip a l dev vlan102
5: vlan102: <BROADCAST,MULTICAST,MASTER,UP> mtu 1500 qdisc noqueue

Where do you see problem?
