Re: dsl modem connection


Our current network setup was a cisco router 2811 with a T1 connection. The serial and the ethernet ports was configured with the T1 and our internal network respectively.

We have 2 dsl lines which are 2.5MB and 1MB and I wanted to combined this dsl's to cater our whole network which are also subdivided via a VLAN.

How can I do that? Please help me. Tnx


Re: dsl modem connection

Can you tell how do you connect two DSL lines to the router ? Do you mean you will have two DSL connection in router and use it to connect to Internet ?

If both DSL lines are connecting to the Internet, you can load-sharing the traffic by enable two default route in the router. But it can only provide out-going load-sharing. The incoming side is depending on the ISP.

Can you describe your requirement in more detail ?

Re: dsl modem connection

Hi Norberto,

As far as I understand from your statements is that, you are happy with your existing connection of the 2811 with T-1 (for WAN) and FE (for Internal LAN). However you want to make sure that the Internet connection which is provided with 2 DSL Lines (2.5 Mbps and 1 Mbps) and want to take the best out of it.

Hence you want to combine both of the DSLs and use it as one Link to the Internet??

If this is what you want to achieve, then the best way to do is to enable BGP, however other than that its quite a difficult to achieve true Load Balancing effect.

Kindly revert back if this doesnt meet your requirements.

Kind Regards,

Wilson Samuel
