Re: Router To Router Slow Connection

arthurjjjc · ‎06-30-2004

Can you help me i got with the slow connection, I have a router in our head office and another one in the warehouse now whem it try to have a continous pinging I get a result sometimes a timeout request. My location is in the head office..and I am trying to access the warehouse but it is too slow..

The leased line bandwidth is 128kbps but still i could not make it work fast enough..The following configuration I made:

Head Office:

Please feeback on this I could not find the solution on this problem..Is there any problem with my configuration?

Please advise..

Are you getting any interface errors on either of the serial links?

This is the result when i used show interface serial 0 for the warehouse router, below is the status I get:

When i try to ping it i got an average of speed of 600 to 700 ms which i think it is not ok with 128 kbps leased line connection..

Is there any problem with my router configuration?

Thanks for your immdiate response..

smif101 · ‎06-30-2004

Ok one thing I would do is to add the bandwidth 128 command to both of those interfaces. Then do a clear counters on both routers. I would then check to see if your input errors or CRC's go up at that point, I don't think there is a problem there because the reliability of the link is 255/255. I am guessing that after you change the bandwidth command you are going to see the load on the interface go up a lot higher which suggests that it is over utilized. You can see under the 5 minute input and output rate that they are at 125000bps and 124000bps respectfully which is your maximum bandwidth. The reason you are getting such high latency times is because the router is overutilized. There is obviously someone or some application that is taking up all the bandwidth.

Hi,

Ok, we use the connection for an application connected from the Head Office accessed by the warehouse..I already put the 128 commands on both interface..About the application it is a JAVA applet that is running the Warehouse System Utility..

Any updates on this I will advise you..

Thanks for the info..

arthurjjjc · ‎07-04-2004

Hi,

Thanks for the information that you gave but I change my configuration to use the Router Rip version and configured both three networks for the Warehouse router and Head office router. Below are the lines I add in order to have a better performance:

Warehouse router:

router rip

version 2

network 192.168.1.0

network 10.10.0.0

network 172.17.17.0

Remove ip route 0.0.0.0 0.0.0.0 172.17.17.1

Note: This configuration makes the router very slow

Head Office router:

router rip

version 2

network 192.168.0.0

network 10.10.1.0

network 172.17.17.0

Remove ip route 0.0.0.0 0.0.0.0 172.17.17.1

Note: This configuration makes the router very slow

Now it is ok thanks also, I based it on another discussion thread in order for this to solved..

denisluo · ‎06-30-2004

Hi,

I don't understand the state route configuration in

your router:

headoffice:

ip route 192.168.1.0 255.255.255.252 172.17.17.2

Warehouse:

ip route 192.168.0.0 255.255.255.252 172.17.17.1

Are U sure the subnet assigned is right?

^-^

smif101 · ‎07-01-2004

Yeah the route statements are messed up but there is a default route on each one pointing to the other which makes it work. I would just get rid of the two statements above or better yet, run a routing protocol.

arthurjjjc · ‎07-02-2004

This is the subnet that was given by our ISP and i think they should know about this..Any way as per your analization of the configuration can you send me a configuration that would fits our setup..

Please advise me on this thanks..

jcharur · ‎07-01-2004

My suggestion is that you Fix the Fastehernet port 100/ FUll or 10/full according to the Switch Port or Hub Port.

arthurjjjc · ‎07-02-2004

Can you elaborate no this I could not understand..

aathomas · ‎07-05-2004

Do this:-

1.Remove the dodgy routes.

2.Configure Weighted Fair Queueing on the 128k serial interfaces -its always a good starter.

3.Why try to run RIP on a simple point to pint link-your just adding to the circuit overhead ?

4.As already mentioned -Nail up your ethernet port speed to match the LAN hub or switch

Try something like

!

hostname kudu-hq

!

etc

!

interface FastEthernet0

ip address 10.10.1.3 255.255.255.0 secondary

ip address 192.168.0.3 255.255.255.0

speed auto

!

interface Serial0

bandwidth 128

ip address 172.17.17.1 255.255.255.252

fair-queue

!

ip classless

ip route 10.10.0.0 255.255.255.0 172.17.17.2
