Hi

I have 2 router 3640 and it have 3 pvc

256K for voice

256K for Data

512K for Video

I use Frame Relay, but went i don´t have videoconference i want to use the pvc of 256K Data + 512K video only both for data, The bandwith of each PVC is setting in the sub interface and i use 3 definition of eigrp one for service. i was probe with only 2 definition of eigrp and apply the variance command , but went i use a traceroute of 1 pc in every site only use one path, in the router the tracer use the 2 path

This is part of the router configuration for use the data and video PVC

router eigrp 1

variance 2

Perphas

I was use mrtg to measure the bandwith and the balance of the it is not proportional 2:1

How i can to verify if the balance is o.k

Try turning of Fast switching, and check the traceroute from the PC. From the PCwhen you do a tracert, the packets are fast switched, and it wil use only one path, because, per destination Load balancing is configure

To turn off Fast switching, you can use " no ip route-cache" under each subinterface.
