Interface atm0, atm0.1, bvi and vlan are all up/up

O2 have verified the vpi, vci, SM settings using LLC

I'm getting a solid cd light but no internet/ability to ping anything even from the router

Can anyone help?

Thanks

J

That was an overlook by my side too. I should have noticed and told you that with bridged RFC1483 you can't have:

ip route 0.0.0.0 0.0.0.0 ATM0.1

Instead, one has to use to the correct default gateway address, as you confirmed.

Try moving the cloned mac under atm0.1

The take show interface atm0.1, show atm pvc 0/101.

Thanks for replying Paolo......

I can't move the mac into atm0.1 (unrecognised command)

I can't switch atm and atm0.1 configs around either for the same reason

But here are the sh command outputs that you needed -

Can you ask O2 if they have a MAC lock and if so, clear it.

Hi Paolo,

O2 do not have a mac lock but thnakfully, the problem is now resolved.  The issue seemed to be as simple as the DG.  Once i pushed all traffic out of the DG associated with the subnet that i was on rather than one that was given to me, everything appeared to work correctly. 

Thanks so much for your help

Regardless, your help was invaluable in getting to the root of the problem.  Thanks so much.

Hopefully you'll be able to help with some further discussions
