hallo
i tried a new configuration : see below
i send this to the keepalived mailing list but no answer yet.
maybe you can spare a few minutes to look at this config.
linux = ubuntu dapper / nic's are from netgear
thanks.
for my thesis i am testing keepalived/vrrp to failover two lans
see keepalived.conf below. (newer config than my first mail)
i'm having problems with pinging to other lan. as a test : i want to use
two ethernet links between two lans with two linux routers
in between using keepalived/vrrp for redundancy.
i want to test this between two lans to failover voip.
the failover works fine. the problem is: i can ping from one lan to the
interfaces in the router. but i can't ping it from the other lan. and i
cannot ping through the loadbalancer to other lan. when i look into my arp
table on a host pc i get the phisical mac address instead of a virtual mac
address. is this normal? the two lan and routers are all in the same
subnet. hope you can help me.
lan ------- switch ----------- linux 1 with keepalived ----------
switch --------- lan2
------------ linux 2 with
keepalived -----------
on linux 1 : eth0 = 192.168.0.50 ; eth1 = 192.168.0.60
on linux 2 : eth0 = 192.168.0.51 ; eth1 = 192.168.0.61
pc on lan 1 = 192.168.0.5
pc on lan 2 = 192.168.0.10

Hi
Both of your messages wrapped horribly, so here's my attempt at unpicking
them:

1. On director 1
vrrp_instance D1 {
state MASTER
interface eth0
virtual_router_id 51
priority 150
advert_int 1
authentication {
auth_type AH
auth_pass TEST
}
virtual_ipaddress {
10.0.0.110
}
}
vrrp_instance D2 {
state BACKUP
interface eth0
virtual_router_id 52

virtual_ipaddress {

}
So that's the configs sorted out. Firstly I would recommend commenting out
the authentication {} sections, unless you are completely sure that this
is working (there's been lots of talk of broken AH mechanisms on the
keepalived list in the last 18 months or so, which may be fixed but
removing it simplifies things anyway).
Unfortunately, the config you give us isn't complete - what other IP
addresses are hardwired onto the interfaces?
Also, if this is strictly a VRRP issue, you may want to discuss it on the
keepalived list instead of the LVS list. I've cc'd that list to kickstart
it.
