Yes you have a routing loop. Have a look on 192.168.104.254 device for a route to 10.2.0.11.

Could you post output of "sh ip route" from this device.

Hello Gandhi,

this is a routing loop:

1 7 ms 1 ms 1 ms 192.168.103.1

2 * <1 ms * 192.168.103.254

these two routers think the other one is to be used to reach the three destinations.

So the packet is sent back and forth between them.

Using the network topology you can understand which of the two routers is in direction to reach nets 10.2.0.0 and 10.1.1.0. (I assume a /24 mask but it is not important here).

Verify if the remote site can reach the remote LAN segments 10.1.1.0 and 10.2.0.0: if it has lost the connected it is sending back the packets using a default route.

May be a LAN switch has been powered off or a trunk link is not working properly

Hope to help

Giuseppe
