Hi,

I am having trouble connecting my 887 to my o2 broadband service.  Here is my configuration -

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

Try moving the cloned mac under atm0.1

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

[Jinesh Patel]

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.

[Jinesh Patel]

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

[paolo bevilacqua · Accepted solution]

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.

[Jinesh Patel]

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
