BTInfinty connection using a Cisco 887a router

beckyboo123 — Tue, 20 Sep 2016 11:27:29 GMT

I am trying to connect my Cisco 887a to a new BTInfinity connection using a static IP. The line works fine with the BT supplied hub but I cannot seem to reach out to the internet when I try the Cisco 887a device.

I am new to routing and Cisco devices so I am sure that I have just forgotten a simple thing. Would anyone be able to take a look at my config and see if anything stands out?

HI beckyboo123

is it just a single static IP your line has? If it is you do not configure this in the router as we auto assign it to the line when the router logs in with the correct username and password for the line.

hope this helps

Hi markp,

Thank you for taking the time to reply, most appreciated.

It is indeed just one single static IP that we have.

I have adjusted to read the following:

interface Dialer1 description vDSL
 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
 dialer pool 1 dialer idle-timeout 0 dialer-group 1 ppp authentication chap pap callin
 ppp chap hostname {ISP-USERNAME-HERE} ppp chap password 0 {ISP-PASSWORD-HERE} ppp pap sent-username {ISP-USERNAME-HERE} password 0 {ISP-PASSWORD-HERE} ppp ipcp dns request accept
 ppp ipcp route default ppp ipcp address accept
 no cdp enable

I'm a little confused now though. If I do a "show ip interface brief" it shows:

Interface IP-Address OK? Method Status Protocol
ATM0 unassigned YES NVRAM down down
Dialer1 unassigned YES NVRAM up up
Ethernet0 unassigned YES NVRAM administratively down down
FastEthernet0 unassigned YES unset up down
FastEthernet1 unassigned YES unset up down
FastEthernet2 unassigned YES unset up down
FastEthernet3 unassigned YES unset up down
NVI0 unassigned YES unset administratively down down
Vlan1 192.168.0.1 YES NVRAM up down

Is this correct? The changes didn't solve the issue, still unable to reach the internet 😞

Hi beckyboo123,

Are you putting the correct username and password to authenticate the line?

the username should look like A123456@hg12.btlclick.com ?

Hi markp,

I have just checked my welcome emails and they appear to be the same.

Is ther any command I can use on the router to see if its attempting to connect but failing on authentication?

Hi beckyboo123

I am afraid it is not a router I can help with as it is not a BT supplied router, you could try contacting our IT Support Managers on 0800 500 247 they can help with non BT 3rd party router, they are a chargeable service.

Thanks for your help markp. I understand and I will see if that is an option for us if I cannot resolve the issue after a few more days of research 🙂

Hi, If your connecting your cisco directly to the wall and not using any BT equipment, you will need to set your VLAN Tag to 101. Unfortunately I am not sure how to do this on a Cisco device.
