Load balancing over two separate outside routers and two separate WAN Links

Thomas Reiling

Hi everybody,

I have one 2851 setup with two separate ISP links and have it configured for failover with BGP.  It works great but doesn't load balance.

Well now I have to new routers (3925's) to replace the single 2851 and I want to configure them to load balance over separate WAN links.

Can someone help figure out the best approach to make this happen?  I would really appreciate it.

Thank you,

Thomas Reiling

We're not using MPLS.  We have two separate Comcast Ethernet connections.

maximum-paths 2 can do the work for you.

The "best approach", IMO, would be to use PfR (if your routers support it).
