2 serial links load balancing

I have 2 2621 Routers and these two were connected via 2 serial links (2Mbps per link). I want to know is that how can I share a traffic between those two so it can sum up a total of 4Mbps. What is the best way to configure this ? Hoping for your prompt response.

Re: 2 serial links load balancing

Hello Jaime,

you can:

use L3 load balancing features having the two links as equal cost paths in the routing protocol in use or using static routes.

But this cannot guarantee a fair load sharing on the links

there are bundling options :

PPP multilink

FR multilink FRF.16.1

I would suggest PPP multilink

Unfortunately I cannot search in CCO it is not working

Hope to help
