Sniffing router !!

Hi,

I need to analyze GRE traffic from serial point to point connection, is there any method to sniff traffic between these two routers?

Is there something like SPAN ports on switches? 3rd party tools may be?

Think you in advance

Depending on the version of code that you are running there may be something similar to SPAN that you can use. The feature is IP EXPORT. You can use this link to find some information about it and how to configure it:

It was introduced as an enhancement for IDS support in IOS and allows you to send copies of data from LAN and serial interfaces. I have not yet used this feature, but it sounds like it does what you need.
