Hi,

If your concern is to load-balance the traffic on the 2 internet links you have to run BGP with your service providers. BGP is the best solution for redundancy+loadbalancing.

If you are not hosting any service internally that need to be accessed from outside, & need to loadbalance outgoing internet traffic only then you may point 2 default routes to 2 ISP's. However, incoming traffic may not be load-balanced.

hope that clarifies.

pls rate all helpful posts.

Configure 2 default routes to 2 your SP for outgoing load balancing and for incoming you can divide your network into 2 groups/subnets or HSRP with 2 groups .

Dear labib,

Load-balance in your case can be achived with tow steps.

Routing step.

1)Configure 2 default routes (0.0.0.0) pointing to each of your serial interfaces (hwic) or sub-interface (the interface where the IP address configured),

also your ISP should configure 2 seperated static routes for your IP address space pointing to both of your interfaces.

Load-balance or load-share step.

2)enable CEF on your router (by default enabled since 12.0) and configure "ip load-sharing per-packet" command on both interfaces or sub-interfaces, also

make sure your ISP have the same config and load-balance method you used.

NOTE: If there is voice traffic running over this interfaces just enabled CEF and leave it with the default load-share method which is (per destination)

Here is your guide to configure CEF.
