Traceroute showing double entry | Really slow connection | C3750G

lap
Level 2
Level 2

Hi Guys,

I have the following setup:

DMVPN_MPLS_Network_Design_CiscoSupportForum_Traceroute.jpg

As you can see when I trace from the remote location to google (8.8.8.8). I have a double entry in the traceroute which I think is strange.

Then I surf the Internet from Remote location (192.168.201.66) although it is a Gig connection the Internet is really slow (2Mbit download).

But I surf the Internet form the HUB site (192.168.107.0) Connection is normal and fast.

One last thing, 192.168.107.1 is the DG for 192.168.107.0 /24 network. 3750G is running EIGRP with Router 1 and Router 2.

Connection between both sites (192.168.201.0 /24 and 192.168.107.0 /24) is working find and it is fast!

Connection from 192.168.201.0 /24 to Internet is amazingly slow!


I suspect it is a routing problem but I cannot find where it could be.

Any ideas?

Regards,

Laurent

Hi Laurent,

I suggest opening a TAC case for this problem since it might require a good deal of troubleshooting and collecting outputs to identify and isolate the problem.

Cheers.

Hello Laurent,

Do you have no ip redirects on the vlan interface which has the 192.168.107.1 ip address?  If not can you turn that on?

Hello Matthew,

Well the interface looks  like that:

interface Vlan1
description ***INSIDE***
ip address 192.168.107.1 255.255.255.0

So I didn't change anything. I have tried to disable CBAC firewall on Router1 and all policy-maps, access-lists and no change at all! I don´tknow where the problem comes from, that is really strange. If I tell the ISP to change the 0.0.0.0 0.0.0.0 192.168.107.1 to 0.0.0.0 0.0.0.0 192.168.107.254 (Virtual IP) than the trace route shows 192.168.107.254 twice in the path!

From 192.168.201.66 if I proxy the Internet traffic to one Proxy-server on the 192.168.107.0 /24 network than the speed is arrong 70Mbit/s and everything works find!

Hi,

The problem is solved by restarting Router1 (C2921).

Quite strange;-)
