2 device for 1 Graph

[Shadow77]

I want to make a graph for display the traffic of 1 router on an other router.

I have 13 router. Some of there router are directly connected on 1 routeur.
I want to see which router consumes how much band-width

I don't know how to do this

to afflict for my English, I am French...

This is possible. Please add all of your routers to the Device list. Provide the correct snmp community string for each of them. Assign the Generic SNMP host template. This will give you the Interface Traffic Associated Data Query.
Then Create Graphs for this Host. You'll see a table of all interfaces found. Check those you want to be graphed. Select the wanted Graph (e.g. 95% Traffic) and Create. You may repeat this last step for all graphs you want to be generated (e.g. unicast packets or the like).
See the docs section at http://www.cacti.net for more.

You dont understand what i want to do.

The traffic by router is OK.

All of router are ISP VPN, and i want to see on 1 router the traffic consumes by the other site. ex :

On Router 1 i want to know how router 2 and how router 3 consume of band-width

Ok. You want to seperate the traffic going from/to different destinations, correct? This will required sth like cflow (search the forum on this, it has already been discussed) in general. But if there is an OID (MIB Table) for VPN traffic (I don't know the Cisco MIBs in detail), this may be done using a VPN XML Query. Please search the Scripts and Templates forum on that, perhaps trhere's already a solution.
