887VA VDSL2 configuration problem

[Kucko]

Hi,

I have 887VA router and trying to configure VDSL internet connection.

VDSL is working, but no IP address is set.

In interface Ethernet0 I was trying to use

ip address negotiated

and also

ip address dhcp

but no one gives me IP.

Internet is working on another non-Cisco router

[balaji.bandi]

make default interface eth0

try below config and let us know.

interface Ethernet0
no ip address
pppoe enable
pppoe-client dial-pool-number 1
no cdp enable
no shutdown

interface Dialer1
mtu 1492
ip address negotiated
no ip redirects
no ip unreachables
no ip proxy-arp
ip mtu 1452
ip nat outside
ip virtual-reassembly in
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 1
dialer-group 1
ppp authentication pap chap ms-chap callin
ppp chap hostname pisarsuk66@dslbasic
ppp chap password 7 15020D04503A2F
ppp ipcp address accept
no cdp enable

Hi,

I was trying both solutions, but no success - no IP was assigned. Yesterday I was finishing at 3:00AM, so I could miss something.

I will review configuration at Monday and give you feedback.

Thanks for your help.

[Georg Pauwen]

Who is your ISP ? What country are you in ?

Post the configuration again with the changes implemented, so we can double check...

[Kucko]

Country is Slovakia, provider T-Com.

Changes was applied.

I was trying also with

no pppoe enable group global

Still no IP assigned

[Kucko]

Afterapplying

--> no pppoe enable group global

This line also dismissed:

pppoe-client dial-pool-number 1

[paul driver]

Hello

Try the Following:

no interface Ethernet0.101

interface ATM0
no shut

interface ATM0.101 point-to-point
no ip address
pvc x/xx < ----isp provides this?
pppoe-client dial-pool-number 1

int dialer 0
shut

no shut

[Kucko]

Paul, I don't think, it's correct configuration. 

Please, correct me, if I'm wrong.

1. As I understand, ATM0 interface is only for ADSL connection. I'm using VDSL2 Annex-A.

Here is info about my connection from my old Asus router:

DSL Modulation	ITU G.993.2(VDSL2)
Regional Mode	A
DSL Exchange(DSLAM)	Infineon(Lantiq)
Current Profile	17a

2. As I can see from my previous logs, VDSL2 link is correctly connected, but only IP address was not negotiated. Today I was checked that protocol is CHAP, I was set it manually.

[Kucko · Accepted solution]

Problem solved.

Only problem was the VLAN ID for VDSL LAN (not 101, but 2510). I found it on T-com pages: https://www.telekom.sk/wiki/internet/zakladne-nastavenia-siete

Correct config is attached.

Thanks for your help

[Georg Pauwen]

Odd...they have been using Vlan 101 for ages...

Glad that you got it resolved, I don't think anybody would have figured that one out...Vlan 2510.
