HI EXPERTS!
If we 2 routers runing GLBP for wan redundancy.this is the config for the 1st active router:
ACTIVE-ROUTER 1
***************
interface fastethernet 0/0
ip address 10.10.100.2 255.255.255.0
glbp 10 ip 10.10.100.1
glbp 10 forwarder preempt delay minimum 60
glbp 10 load-balancing host-dependent
glbp 10 preempt delay minimum 60
glbp 10 priority 254
glbp 10 timers 5 18
glbp 10 timers redirect 600 7200
glbp 10 weighting 110 lower 95 upper 105
glbp 10 weighting track 2 decrement 5
!
track 2 interface f0/1 ip routing
waht could be the config for the Standby router(ROUTER 2) based on the first input?
STANDBY-ROUTER 2
??????????????

Hi Ali
First i think you need to make a change to your active router config.
i think you probably want to change
track 2 interface f0/1 ip routing to
track 2 interface f0/1 line-protocol
You also need to adjust your weightings. If f0/1 goes down it will not switch because you are only taking 5 off the weighting and this does not take it below 95.
So change
glbp 10 weighting track 2 decrement 5 to
glbp 10 weighting track 2 decrement 20
110 - 20 = 90 which is less than your lower threshold of 95.
For the other router
interface fastethernet 0/0
ip address 10.10.100.3 255.255.255.0
glbp 10 ip 10.10.100.1
glbp 10 load-balancing host-dependent
glbp 10 priority 100
glbp 10 timers 5 18
glbp 10 timers redirect 600 7200
glbp 10 weighting 110 lower 95 upper 105
glbp 10 weighting track 2 decrement 20
!
track 2 interface f0/1 line-protocol
I hope this works -please let me know if you have any problems.

glbp 10 priority 254
glbp 10 timers 5 18
glbp 10 timers redirect 600 7200
glbp 10 weighting 110 lower 95 upper 105
glbp 10 weighting track 2 decrement 20
!
track 2 interface f0/1 line-protocol
!
STANDBY-ROUTER 2{AVF}
*********************
interface fastethernet 0/0
ip address 10.10.100.3 255.255.255.0

Hi Ali
You would need a default route on R1 & R2 pointing to the releavant ISP wireless address but your clients will be fine.

HI Jon
Like this:
R1
ip route 0.0.0.0 0.0.0.0 f0/1(ISPA:202.10.10.1}
R2
ip route 0.0.0.0 0.0.0.0 f0/1(ISPB:194.126.10.10.1}
any comments?

Hi Ali
If the links are P2P links then you can use either interfaces or ip addresses as next hop. if not then use IP addresses.
As for Glbp config - looks fine to me. You might want to add a "glb 10 preempt ..." command on R2 but it won't make any difference really as it has a lower priority anyway.
Let me know how it goes
