load balancing wireless and serial link

Hi..

I have a customer site with 2 connectivity, one is wireless and other is a serial line. How can i load balance between them.

thanks and regards

Re: load balancing wireless and serial link

Hello Rajesh,

you can achieve load balancing,

with static routes

ip route 0.0.0.0 0.0.0.0 serx/y

ip route 0.0.0.0 0.0.0.0 type z/k

with routing protocols you may need to adjust some parameters to have the two links used in the same way.

However, if the two links have different speeds it can be better to implement a scheme with a primary and a secondary link

with static routes

ip route 0.0.0.0 0.0.0.0 serx/y 201

ip route 0.0.0.0 0.0.0.0 type z/k

let's suppose that wireless link has more bandwidth.

For OSPF you need to adjust the bandwidth parameter with interface command

bandwidth XX [kbps]

For EIGRP the better way is to modify delay with interface command

delay yyyy [microseconds]

With EIGRP you could also try to use the variance command to get weighted load balancing if the secondary link passes the feasibility test

Hope to help

Giuseppe
