Load sharing

I have two link the first one is leased line 1 Mbps and the second  is ADSL wiht 1Mbps
the leased is connect to cisco router 2811 with serial interface .
the second is connect to linksys E2000 .
I want to create  load sharing between the two link
my idea is to connect linksys router ADSL to cisco Router through ethernet port and do load sharing between the two link .is that possible or i need to do it in other way .

the cisco can do per packet load balancing, but this needs to be over two lines to the same ISP with support from the ISP

To do outbound load balancing over two different ISP connections, you need to use something else.

I would suggest using a PC with three network cards (or configured with VLANS and suitable managed switch) and installing pfSense on it

ArneLoviusCommented:
even if both connections are from the same ISP, unless they support load balancing it will not work with the Cisco.

for it to work, your address block must be addressable over both connections, the Cisco can then send outbound packets over both connections, however as one is a leased line and the other is ADSL this will lead to issues as the latency will be very different over each connection. this is why I would suggest a "dedicated" outbound load balancer.

ArneLoviusCommented:
yes, you could configure failover, but a load balancer between the two routers and the LAN would be a better option.
