I am setting up a condo with a Cisco 3640 and a 200 port DSLAM. Currently it would take 6 months to get a fiber link to the building (no fiber in the area). We would like to get the place up and running fast and opted to install multiple ADSL lines. We will be offering VoIP services too for all 200 tenants.
The Cisco 3640 will be configured as a PPPoE Concentrator. It will dial out via multiple PPPoE ADSL lines.
The questions I would like to know are:
- How would I be able to load balance the traffic over multiple ADSL links in both directions without using NAT.
- Forward Voice traffic over another specific set of ADSL Lines load balanced as well.
We will be temporarily using the inexpensive technology until the fiber is put in place.
Thanks for any replies.
if you have a LAN switch you can use VLAN subifs on the router via a trunk port to connect to external ADSL routers/modems each of them is placed in a different Vlan.
But you cannot have pppoe client on each subif and what is very important you cannot use ip addresses in the same IP subnets on different LAN/Vlan subifs or ifs
So the ADSL devices have to be routers and different IP subnets have to be used.
In this case you can configure default routes with next-hops the ADSL routers lan interfaces.
To use a routing protocol is possible if you can configure the ADSL routers.
Hope to help
