Hello,
I'm trying to setup keealived on a vlan router and I've got few setup
problem ...
I've got 2 vlan routers that interconnect 7 VLANs. My default gateway is
configured on VLAN800. The management VLAN is VLAN500.
When my master is down the backup take the relay without problem. But
when I reconnet the master, the "slave" doesn't hand control to the
master...
I need to have a virtual IP on each VLAN. So I've setup only one "vrrp
instance" in keepalived.conf with "virtual_ipaddress" block with each
virtual IPs.
Maybe I must setup various "vrrp instance" (one per VLAN) ?
Moreover a "netstat -lp" tell me that vrrp listen on all interfaces
"*" ... How can I restrict this to only one (vlan500)
# netstat - lp
...
raw 0 0 *:vrrp *:*
7 2087/keepalived
raw 0 0 *:vrrp *:*
7 2087/keepalived
raw 0 0 *:255 *:*
7 2087/keepalived
raw 0 0 *:255 *:*
7 2086/keepalived
I'm not sure that these parameters are required :
advert_int 1
lvs_sync_daemon_interface vlan500
Thanks for your help. I've tried to put maximum of details about my
configs. I hope that someone could give me a hand.
Regards
Sebastien
