Uneven distribution on multilinks using CEF

[admin_2]

Hi all,

We've been having a problem recently with the way CEF is working on our 2611. What we've noticed is that on outbound traffic, one T1 is preferred significantly over the other 2 T1's. Sometime's we'll have as much as 94% utilization on the one link while the others are just at 1% utilization.

Inbound traffic is load balanced much more evenly. We're setup with per-destination as we run videoconference over our WAN. In terms of source-destination pairs, there are approximately 6, reflecting our 6 different regional offices (we have a fully meshed VPN over the internet).

Any clues?

It looks natural for per-dest load-balancing. If per-packet load-balancing is not an option, you can try to decrease delay of the your outbound I'm assuming that uyou're using EIGRP allowing unequal cost load balancing). This way you can metric of networks seen through those two links nad can check yhis using "sh ip route "

Regards.
