Hi,
i have installed a 2911 router (15.0 IOS) with a G.HSDSL module. i have configured a controller and an ATM interface with specific parameters.
!
controller SHDSL 0/0/0
dsl-group 0 pairs 0
shdsl annex A
shdsl rate auto
interface ATM0/0/0
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
no atm ilmi-keepalive
!
!
interface ATM0/0/0.1 point-to-point
description ADSL OGERO
mtu 1500
bandwidth 1000
ip address x.x.x.x x.x.x.x.
no ip redirects
no ip unreachables
no ip proxy-arp
atm route-bridged ip
crypto map DSL
pvc 0/35
the problem is that the connection stays up up for 2 or 3 days then it goes down for few minutes. i don't know how to solve the problem and i doubt it is the configuration, mean how the link works for long time and then goes down,
If anyone have a clue please i need some help.
On the other hand, i coordinated with the provider and agreed to use an external modem to do test the line to see if there is any physical problems on the line. so i shut down the ATM interface and connect the modem to the router with ethernet port and assigned an the ip address of the ATM interface to the ethernet.
the line was up up but there is no connectivity , no neighbor was discovered (eigrp).
the question is , do i have to add other commands in order to establish connectivity between the 2 sites.?

If I understand correctly, the service providers modem is more than likely not a Cisco device so you will not see EIGRP neighbors. What you will need (if I understand correctly) is for the service provider to bridge their modem (which they may have done), the public ip address on your ethernet port (sounds like you have done already), a default route pointing to the gateway that the service provider gives you, and NAT.
Again, I may not get this example because I dont even see NAT on your posted config.
OK, I see what your doing now. Sorry about the bable above.
I would think that as long as the modem was bridged (it must be if you have a public IP on your ethernet interface and you can surf) and your crypto map and IP's were applied that everything should work.
