Hi,
I have this configuration on two routers:
Router 1
interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 10.1.120.254 255.255.255.0 secondary
ip address 10.1.6.163 255.255.248.0
ip helper-address 10.4.0.51
ip helper-address 10.4.0.52
ip accounting output-packets
ip accounting access-violations
service-policy input MARKING
no ip mroute-cache
no cdp enable
glbp 10 ip 10.1.6.162
glbp 10 ip 10.1.120.1 secondary
glbp 10 preempt
glbp 10 load-balancing weighted
Router 2
interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 10.1.120.253 255.255.255.0 secondary
ip address 10.1.6.164 255.255.248.0
ip helper-address 10.4.0.51
ip helper-address 10.4.0.52
ip accounting output-packets
ip accounting access-violations
service-policy input MARKING
no ip mroute-cache
no cdp enable
glbp 10 ip 10.1.6.162
glbp 10 ip 10.1.120.1 secondary
glbp 10 priority 254
glbp 10 preempt
glbp 10 load-balancing weighted
end
but a show glbp int show that just one forwarder is active int group:
sh glbp f0/0.1
FastEthernet0/0.1 - Group 10
State is Active
7 state changes, last state change 1w3d
Virtual IP address is 10.1.6.162
Secondary virtual IP address 10.1.120.1
Hello time 3 sec, hold time 10 sec
Next hello sent in 0.520 secs
Redirect time 600 sec, forwarder time-out 14400 sec
Preemption enabled, min delay 0 sec
Active is local
Standby is 10.1.6.163, priority 100 (expires in 9.480 sec)
Priority 254 (configured)
Weighting 100 (default 100), thresholds: lower 1, upper 100
Load balancing: weighted
There are 2 forwarders (1 active)
Forwarder 1
State is Listen
2 state changes, last state change 1w4d
MAC address is 0007.b400.0a01 (learnt)
Owner ID is 0002.2c80.4100
Redirection enabled, 599.476 sec remaining (maximum 600 sec)
Time to live: 14399.476 sec (maximum 14400 sec)
Preemption enabled, min delay 30 sec
Active is 10.1.6.163 (primary), weighting 100 (expires in 9.476 sec)
Arp replies sent: 80876
Forwarder 2
State is Active
5 state changes, last state change 1w3d
MAC address is 0007.b400.0a02 (default)
Owner ID is 0002.2c79.e000
Redirection enabled
Preemption enabled, min delay 30 sec
Active is local, weighting 100
Arp replies sent: 80874
In this case I don't have load balancing.
Someone can give my an advice?

Have you tried leaving the 'glbp 10 priority 254' statement off router 2 to see if it impacts glbp at all?

glbp will just route traffic to both routers but dis will be done on the weight u specify.for example in your sample, if one packet goes to one router about 2.5 will go to the next router. it is simply routing over un-equal path here, kind of. If u want load-sharing u either use a 3rd-vendor like f5 or u use cisco oer.
