PPP can insert a dynamic default route whenever IPCP negotiations succeed (and remove it when the line protocol goes down). To configure this feature (introduced in IOS releases 12.3(11)T and 12.4), use the <code>ppp ipcp route default</code> interface configuration command on the primary dialer interface.

o2 broadband configuration

o2 is one of this UK odd ISPs who is using RFC 1483 Bridge when providing ADSL2+ Internet access. Below are details provided by O2 and config build on this information. 

ISP name: O2 Home Broadband  
Encapsulation: RFC 1483 Bridged
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
My o2 box MAC address: 00-24-17-80-42-d0
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. Read more on Cisco Community
Integrated Routing and Bridging
bridge irb command enables Integrated Routing and Bridging, then sub-interface atm0/1/0.1 and gi0/0 belong to the same Bridge Group 1 having both bridge-group 1 in their interface configurations. BVI1 (bridge virtual interface) is configured to represents both atm0/1/0.1 and gi0/0 interfaces when ip protocol is routed. Two lines at the bottom bridge 1 protocol ieee and bridge 1 route ip define the Bridge Group 1 is using IEEE bridge protocol and routes IP protocol.

Below config is working with O2 as of 8th Oct 2013, public ip address is provided by ISP dhcp server. Please see sub-interface atm0/1/0.1 command ip address dhcp therefore static ip route something like ip route 0.0.0.0 0.0.0.0 O2_gateway_ip is excluded. Please think about both commands when configuring static IP address given by O2.

Please notice that static ip route has been excluded because ip address and default gateway are optained from ISP dhcp server. Here default gateway is: S 82.132.253.115 [254/0] via 93.96.104.1, ATM0/1/0.1. This command is not needed for dynamic public IP address assignment via DHCP since that's the whole point of using DHCP. In other words, the default gateway should appear in routing table due to DHCP process with the ISP and not by manual configuration. The only time you need to manually configure the default gateway using DHCP is when you need to change the route administrative distance into something that fits your need. Should this be your choice, the command is the following:ip route 0.0.0.0 0.0.0.0 dhcp [ENTER NEW ADMINISTRATIVE DISTANCE HERE] Reference: Configure router with integrated ADSL modem as DHCP client
