SNMP Track on an MPLE-PE

[siljugpillai]

Hi,

I am getting the following error message on the MPLS-PE router. As there are lot of customers with same ip address (in different vrf) how do I trace which customer is sending the snmp requests. Is there any quick method to resolve this issue.

Thanks,

Silju

Hi Silju,

I don't think that this customer is behind any of your vrf, it should have a direct ip connectivity to your network........ so check in your network do you have any pc or server which is sending/doing snmp to your box with that ip address.....

Rate if it does,

Hi Balaji,

Thanks for your reply. Its coming from a vrf.We dont use 192.168.0.0 range anywhere in the network. We use that subnet only for customers.
