Cisco router configuration for a Tele2 VDSL connection

I got myself a Cisco 887V-W to replace the Comtrend modem that Tele2 ships with their 50 Mbit VDSL connection, once called Fiber Speed. Thanks goes out to Glazenbakje for a basic VDSL config that I could tweak to get it to work with Tele2.

I’d advise to upgrade to IOS 15.1T as it holds a newer ADSL firmware that does a better job calculating the attainable rate. If you connect your router and execute the sh controllers vdsl 0 command you’ll see something like this that indicates you have a VDSL carrier signal:

Modem Status: TC Sync (Showtime!)
DSL Config Mode: AUTO
Trained Mode: G.993.2 (VDSL2) Profile 17a
TC Mode: PTM
Selftest Result: 0x00
DELT configuration: disabled
DELT state: not running
Trellis: ON  ON
Line Attenuation:  0.0 dB  0.0 dB
Signal Attenuation:  0.0 dB  0.0 dB
Noise Margin:  6.2 dB  5.8 dB
Attainable Rate: 44884 kbits/s 5535 kbits/s
Actual Power: 14.2 dBm  1.4 dBm

And now for the basic config lines to get this going:

interface Ethernet0
no ip address
!
interface Ethernet0.32
encapsulation dot1Q 32
pppoe-client dial-pool-number 10
!
interface Vlan1
ip address 10.1.1.34 255.255.255.0
ip nat inside
ip virtual-reassembly in
ip tcp adjust-mss 1452
!

interface Dialer 10
mtu 1492
ip address negotiated
no ip redirects
no ip unreachables
no ip proxy-arp
ip nat outside
no ip virtual-reassembly in
encapsulation ppp
ip route-cache policy
dialer pool 10
dialer string 555
dialer-group 10
ppp authentication chap callin
ppp chap hostname <username>@3p.versatel.nl
ppp chap password 0 <your decoded password>
no cdp enable
!
ip nat inside source list 101 interface Dialer10 overload
ip route 0.0.0.0 0.0.0.0 Dialer10
!
access-list 101 permit ip 10.1.1.0 0.0.0.255 any
dialer-list 10 protocol ip permit

Notes of interest: The VLAN ID that Tele2 uses for their internet connection is 32. They have different ID’s for i.e. the management connection to the modem but you don’t need those. They use CHAP for their PPPoE identification and I needed to use a dialer string with a random number to trigger the dial out.

In case you have any questions feel free to leave a comment and I’ll try to answer to the best of my ability.
