Hi,
How can I make load sharing via 2 routers with GLBP.
I configured GLBP in 2 routers, but they function in redundancy (Active/Standbay), not in load sharing( I mean Active/Active).
thnx

Have a look at this link -
If it is still not working after you have configured a load-balancing option then please come back with configs.

thanks for your response.
let me explain the architecture that I want to implement.
My Lan is behind a PIX, I have 2 routers connected to 2 ISPs.
I configured GLBP in routers (I tried Round robin and weighted), and I added a default route in the PIX to the GLBP address.
I issue a tracert from many hosts in the LAN to Internet, the result is the same from all hosts.

Ah well then it won't load-balance. The issue you have is that the routers always see the same mac-address which is the mac-address of your firewall. So this mac-address will always be sent to the same router.
The mac-addresses of the hosts in the LAN are irrelevant because the routers only see the firewall mac-address.

is there any other solution?

The pix is not really designed to do load-balancing between 2 ISP's.
You can either
1) use a router on which you could implement PBR or have 2 default static routes
OR
2) if you want to use the pix then look into using OSPF between the pix and the 2 routers.

If I use 2 static routes in the PIX with the same metric, How it will manage the traffic?

The pix is not designed to handle 2 default routes with the same metric and load balance between the two. For that you need a router.
Like i say OSPF may be the only solution for you.

thanks for your assistance.
I will try to do it via OSPF, and I'll keep you in touch.

No problem, let me know how you get on.
