Re: BGP unequal load balancing

Follow up question...
Always wondered how bgp's unequal load sharing worked with cef. Since the traffic count will be unequal when using this feature, is the router now performing per packet load sharing?

Example, with two paths (unequal)

The traffic count for 1st will be, say 5.
The 2nd is 3.

Wouldn't this lead one to believe that the router is load sharing per packet instead of the default flow based?

Hey Ali,

Try using the "dmzlink-bw" command on your neighbor statements and the "bgp
dmzlink-bw" command within the BGP process. Also, you'll need to set
"maximum-paths" to 2 (or higher)from within the BGP process (to enable
load-balancing).

Hello Experts,
 Is there a method *unequal* Load Sharing When Dual-Homed to One Internet
Service Provider (ISP) Through a Single Local Router?

I have 2 links to the Service Provider (20MB and 6MB). I am recieving the
full internet routing table from both links I need to load balance with a
ration of 20 : 6 is that possible?
