I am trying to configure an 877 on my home network in the UK. I have just switched provider to 02 as they will let me use my 877 router & Sky would not. However they do not support the cisco router & are not very helpful with information re the config. I am having issues with IP connectivity, layer 1 is fine & i can do an ATM ping no problem. It appears to be a PPP negotiation problem, but the only info i can get from them is that the username & password should be blank. I have been assigned an IP address, but have also tried configuring the dialer interface for "ip address negotiate".
When i do a show ip int brief, all interfaces are UP UP, except for virtual-access2 that is UP DOWN. Any ideas??
