How are these redundant paths connected? Are you running BGP with your upstream providers and between those routers? Do you want it balanced in and outbound? Have you looked at how your routes appear on route servers?
If you setup the BGP peering correctly, you should see some relatively balanced traffic, assuming both upstreams are relatively equivalent in their peering relationships with others. What types of tables are you accepting? All routes, and default, customer only, or just a default? Each router is only going to take its best path to the Internet. So, most likely, you will need to do a bit of work to distribute the load equally. Keep in mind, BGP does not load balance, it load shares. Beyond that, you need to make sure the routing up to your Internet routers is distributed equally, if all the traffic goes to Router1, it will probably exit that router, if it has the best path to the Internet. Finally, if you really need specific load balancing, you might want to look into third party load sharing solutions like Cisco PFR. This all sort of depends on your requirements, budget, and amount of effort you want to spend on the solution.

Streiner Sent: Monday, April 19, 2010 2:29 PM To: juniper-nsp@puck.nether.net Subject: [j-nsp] equal-cost multipath using two DS3s I have an M10i connected to an M7i at a remote location using two DS3s. Attempts thus far to get traffic to share both links relatively evenly have not gone well. All of the traffic will typically use only one of the links, so it gets saturated while the second like is barely even touched. JTAC suggested per-packet load-sharing, however I would like to avoid that because of the possibility of packets arriving out of order which could make latency/jitter-sensitive applications (IP video conferencing, etc) unhappy. JTAC later suggested that per-packet load-sharing in JUNOS parlance doesn't necessarily mean per-packet load- sharing (naturally :) ). Multilink bundles do not appear to be an option without link services PICs, and even at that, they don't seem to be built to work with traffic levels greater than a few T1/E1s. Both routers are running JUNOS 8.5R4.3. That being the case, if anyone has had to deal with a situation like this, I'd be interested in hearing how you addressed it. jms _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp This email may contain confidential and privileged material for the sole use of the intended recipient.
