Hi
Our network works over our ISP's IP VPN cloud and we are running BGP. We have several sites connecting to our main area centre.
We have a device(eg laptop) at site X which connects to a device(laptop) at our HQ. If we make the device(site x) x.x.x.1 /30 and our router interface x.x.x.2 /30 and try to do a simple file share over the network the link is extremely slow,400 - 500bps, yet if we swap the IP's around,ie device x.x.x.2 and our router interface x.x.x.1, then the connection is fine. We are blaming our ISP and they are saying it's our configuration that is the problem. I have tried different routers and there is no difference. We had a CCIE at our office last week and he couldn't understand the problem!
All our links work over fibre and terminate on a Hauwei Echolife ONU.
Attached is a partial configuration of a router at one of our sites.
Is there anyone that has perhaps had a similar problem over IP VPN?

Can you post "sh int fa0/0" and "sh int fa0/1"?

I will do so when I get to the office in the morning(I work in Abu Dhabi)
Thanks!!

Not a lot of data on the port as I was busy testing the link with Vanguard routers before I copied the config's.

For starters, I would hardcode the duplex and speed settings. Try that and see if it helps. You don't have any CRC errors, which is usually and indication of mismatched duplex settings, but I would hard code to say the least.
I would also connect the routers the way that they're connected when you're having the problem, and then repost the "sh int" with the "slow" interface. I'm assuming that the slow interface is f0/1 when it's connected to the inside?
HTH,

Hi John
Thanks!
I'll post the configs tomorrow but it really doesn't matter how long the routers are connected. As soon as I connect them with this specific configuration the transfer between the 2 devices,both connected to the fa0/1interfaces, is slow. If I swap the the IP's around between the device and it's interface(fa0/1) then there's no problem!
Cheers
Greg
