2MB WAN

Hi Guys,


Forgive me if this is the wrong forum.


I have a 2MB P2P line between two offices, the link is provided by NTL and on each end I has a

Cisco2621XM router with a WIC interface connected to the media convertors.


The problem i have is that most of the infrastructure, primary domain controllers, dns, dhcp, user profiles etc.. are located in the HQ and remote users are logging into client machines at the sub-office. When users login at the sub-office it can sometimes take upto an hour for a users profile to load and these profiles are no more than 500MB.


I've had NTL in to look at the P2P line three times and now im looking at the hardware/config of the routers and wondering if you could help me.


Any suggestions welcome

Cheers

Darren

I see several things to comment about though I am not sure that I see the problem clearly.

On the BAT router the RIP configuration has network statements for 192.168.1.0 and 192.168.2.0. It does not have a network statement for 192.168.3.0 which is the serial interface and I can not find any network 192.168.2.0 on the router.

Simmilarly on the HUD there are RIP network statements for 192.168.4.0 and 192.168.5.0 but not for 192.168.3.0.


Another thing that puzzles me is that the BAT router has an ip helper address pointing to an address on the FastEthernet of HUD and that HUD has an ip helper address pointing to an address on the FastEthernet of BAT. Why are the routers pointing helper addresses at each other? And why are there helper addresses configured on both serial interfaces. I doubt that helper addresses on the serial hurts anything, but it does not good.


I also note on the HUD router that the FastEthernet has its speed and duplex specifically set. This will prevent negotiation with whatever device is connected to that interfade (I am guessing some switch). If the other device is configured to negotiate speed and/or duplex then negotiation will fail, the other device probably assumes half duplex operation. The mismatch of duplex will contribute to poor performance.


Perhaps resolving some of these things may help to solve your performance problem. (I do not see anything configured that should impact the serial interface

what is the out from the sho serial interface.

Also does one one of the media converters provide clocking, can get errors if both have been setup to provide clocking

I do notice one thing in the output that you posted:

on the BAT router is this: Total output drops: 1465247

There is not many output drops on the other router. Is BAT the router where the users are experiencing problems?


Perhaps posting the interface configurations might be helpful.
