SHDSL configuration on 2800 Router

t4tauseef33 · ‎01-21-2009

I need 4 SDSL ports on the 2800 router. Is i have to buy 4 WIC-1SHDSL-V3 cards for that?

Secondly Can you please provide me the template configuration to configure the router for SDSL link?

What information i need to get from the ISP to setup this link?

your help will be highly appriciated.

Thanks

Hello Tauseef,

1) yes you need 4 WIC

2) exact configuration varies an example can be

http://www.cisco.com/en/US/docs/routers/access/1800/1801/software/configuration/guide/pppoanat.html

3)

you need to ask the following information:

atm parameters: Vpi/Vci to be used these have values that vary from provider to provider so you need ask to yours

typical values are 0/35 or 8/35

type of service: PPPoA like in example above, PPPoE or IP over ATM this can include authentication data username. password and protocol (pap, chap, ms-chap)

Hope to help

Giuseppe

Hi,

Thanks for your reply. Its really helpfull Can you please also help me how to bundle these 4 SDSL lines together. I want to use all of these 4 sdsl lines as one link. how the ISP provides the bonded service.

Thanks

Since you have only 4 SDSL lines you can buy only 2 WIC's as the mentioned WIC supports 4-Wire mode. And you can arrange with your service provider to provision double speed links over 4-wire. Also it can work as separate 2wire lines over a single WIC

Regarding the bundling of the 4-links I think that you can use a tunnel interface between your router and service provider router but you should 1st check the service provider bundling policy.

Thanks,

By googling, i came to know that there are few methods of bonding

1) PPP Multilink

2) Static Routes load balancing

3) Tunnel interface

Is there any other way of bonding them together and which one is the best?

Routing load balancing (doesn't need to be static) is ok in most situations. Note 3) requires 2)

mszeftawy · ‎01-29-2009

If both the 4 links have the same BW then you can load balance over these links using static route also you have to inform your service provider to load balance the return traffic

And you can also create a tunnel interface that runs over the load balanced links, and that will act as a bundle for the 4 links and in case of adding any routes (Dynamic or static) you have to use the tunnel interface and that will handle the load sharing over the 4 links.

But before using the load balancing and bundling you have to enable ip cef and choose load sharing technique (per-packet or per-destination). And that depends on your traffic type.

For bundling try this:
