ADSL on a CISCO 827
|
|
|
| I have a Cisco 827 router that I have configured for ADSL with the PPPOE config. Know this is the first Cisco ADSL router I have worked on so I was not sure about the config so I went to Cisco's site and found a great sample config. I copied the config and changed the stuff like user name and password to login but the router does not try to connect to my ISP I can see that ATM0 is up up na the dialer is spoofing but it acts like I am not sending intresting traffic out of the interface so it does not try to connect. All interfaces say up but I cannot ping out because it never connects so I dont get a IP adress from my ISP. | |

| This is the config I used.
!
vpdn enable
no vpdn logging
!--- default
!
vpdn-group pppoe
request-dialin
!--- we are the PPPoE client requesting to establish a session
!--- with the aggregation unit (6400 NRP)
protocol pppoe
!
!--- internal Ethernet network
!
interface Ethernet0
ip address 10.92.1.182 255.255.255.0
ip nat inside
!--- DSL interface
!
interface ATM0
no ip address
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
hold-queue 224 in
!--- all defaults
!--- PPPoE runs on top of AAL5SNAP, but the
!--- encap aal5snap command is not used.
!
interface ATM0.1 point-to-point
pvc 1/1
pppoe-client dial-pool-number 1
!--- pvc 1/1 is an example value that must be changed
!--- to match the value used by the Internet Service Provider (ISP)
!
!--- The PPPoE client code ties into a dialer interface upon
!--- which a virtual-access interface is cloned.
!
interface Dialer1
ip address negotiated
ip mtu 1492
!--- Ethernet MTU is 1500 by default -- 1492 + PPPoE headers = 1500
ip nat outside
encapsulation ppp
dialer pool 1
!--- ties to ATM interface
ppp authentication chap callin
ppp chap hostname <username>
ppp chap password <password>
!
!--- Note: The ISP will instruct you regarding the type of authentication to use.
!--- To change from PPP CHAP to PPP PAP, replace
!--- ppp authentication chap callin
!--- ppp chap hostname <username>
!--- ppp chap password <password>
!--- with
!--- ppp authentication pap callin
!--- ppp pap sent-username <username> password <password>
!--- For NAT we are going to overload on the Dialer1 interface
!--- and add a default route out since dialer ip address can change
ip nat inside source list 1 interface Dialer1 overload
ip classless
ip route 0.0.0.0 0.0.0.0 dialer1
no ip http server
!
access-list 1 permit 10.92.1.0 0.0.0.255
!--- for NAT | |
|
| interface ATM0.1 point-to-point
pvc 1/1
This was my problem I had the wrong pvc in there.
There was two pvc I had to add but it is up and working great now I am going to make it connect to a pix via VPN......I hope. |
