Can 2 different MLFR bundles from different PA cards be configured to a single access router and balance traffic across both bundles?

Unanswered Question
Feb 18th, 2010

I work for an ISP that connects educational customers to our network. We ocassionally run in to a situation where a customer needs multiple T1's, but unfortunately not all of them can come from the same PA card on the distribution end. We have set up mflr bundles coming from the 2 different PA cards, but the traffic is not balancing across those 2 bundles very well. Is there additional config needed for this kind of set up?  Thanks,

I have this problem too.

Hello Glen,

you should be able to setup MFR bundles also using ports from different PAs if you use a C7200 or other SW based router.

This is probably not possible with the flexwan on C7600/C6500

if you define two bundles you then have two L3 interfaces and CEF will balance over them

Hope to help

Thanks for your reply, we use Cisco 7609 for the dist router, and a 2811 for the access router. One Mflr bundle will max out, while the 2nd bundle is only at 50% capacity. Not a very good balance of traffic for this configuration.
