o2 broadband configuration

o2 is one of this UK odd ISPs who is using strange Bridged routing when providing ADSL2+ Internet access. Below are details provided by O2 and config build on this information. 

ISP name: O2 Home Broadband  
Multiplexing method: LLC-Based  
VPI: 0  
VCI: 101  
Username: leave blank  
Password: leave blank  
Domain name: leave blank  
IP address type: this depends on whether you chose our static IP address option or not:
    If you didn't choose our static IP address option, set this to dynamic IP
    If you did choose our static IP address, enter the IP address printed in your welcome letter  
DNS servers: choose to get these dynamically from the Internet provider  
NAT: enable  
Primary DNS server: 87.194.255.155  
Secondary DNS server: Leave blank 

If you have a static IP address, you should enter the following DNS server address:
Primary DNS server: 87.194.255.154

This is config for O2 ISP who is using RFC1483 Pure Bridging. A word of bridging explained:

A BVI (Bridged Virtual Interface)is a virtual interface that acts like a normal routed interface. A BVI does not support bridging but actually represents the corresponding bridge group to routed interfaces. The interface number is the link between the BVI and the bridge group. Think of the BVI as the default gateway to all the bridge interfaces, all local traffic is bridged between the bridge interfaces, but the traffic that is not local to the bridge group is routed via the BVI interface.

BT ADSL2+

General settings for broadband modems/routers:

  • radius ppp username: broadband.user@btbroadband.com [provided by BT]
  • radius ppp password: it is not required as BT uses the phone number you're connecting via for authentication but if your router still shouts for one, use: 'BT', 'password', 'password1'
  • VPI number: 0
  • VCI number: 38
  • Authentication: CHAP
  • Modulation: G.DMT
  • Encapsulation: PPP over ATM (PPPoA); Virtual Circuit Multiplexing (VC-MUX)
