what are you using chap or pap from ISP ? Did you get there credentials you will need them to authenticate on their line

Do you have a fixed public ip address or dynamic off them ?

HI Mark 

Thank for your respond .

ISP provided me the credentials to authenticate the PPPOE and we dont have fixed public IP ,its dynamic only

Jawhar

This is what you need obviously replace your ips , acl no etc and add your passwords and stuff but the syntax is what you need for pppoe to connect to ISP negotiate authentication and then pull itself an ip address

Ah great glad you got it sorted , some of the ISPs use that vpdn group but its not a necessity all the time as you seen for your setup :)

[jawharcisco]

Thanks for your info.

Hi Guys,

I'm trying to configure PPOE on the WAN interface of the cisco 881w router.  Issue is the WAN interface needs to be on VLAN 10.  Can anyone advise?

[Georg Pauwen]

Hello,

you need to use a subinterface. Post your current configuration so we can fill in the necessary bits and pieces...

[riaanptrs]

Hi thanks I'll try the subinterface and will let you know if I come right. BTW do you know if I can do ICND 1 and ICND2 and then become CCNA. Also I am actually CCNA certified but cert has expired. Can I go that path to renew my certification?

[Georg Pauwen]

Hello,

subinterface should look like below.

interface FastEthernet4.10
description #phisical WAN interface #

encapsulation dot1q 10
bandwidth inherit
no ip address
no ip redirects
no ip unreachables
no ip proxy-arp
ip flow ingress
duplex auto
