DSL config

I am planning on bringing a new site online but this site will be provided with a DSL line. The current network design is spoke-hub (Hub router 3600 with ATM, egirp as the routing protocol) I would like to know how to configure a new router, Cisco 1841, with DSL to connect via point-to-point to the hub router.

Re: DSL config

Your DSL provier is bridging this back to you over an ATM PVC and you're mapping the PVC to a BVI with an IP in the hub right?

If your DSL provider is handing you an IP then ignore this post.

On the 1841, put an IP in the same subnet on an Ethernet interface.

For example:

On an 8510 switch:

atm pvc 2 32 interface ATM0/0/0 2 32

On "hub" router:

interface ATM3/0.32 point-to-point

description *** xxxxxxxxxxxx ***

bandwidth 640

bridge-group 232

bridge-group 232 spanning-disabled

pvc 2/32

encapsulation aal5snap

interface BVI232

description *** 640K DSL xxxxxxxxx ***

bandwidth 640

ip address x.x.x.1 255.255.255.0

ip route-cache flow

On remote 1841 router:

interface Ethernet1/0

description *** 640K DSL to xxxATM3/0.32 - BVI 232 ***

bandwidth 640

ip address x.x.x.2 255.255.255.0

half-duplex
