Hello,
I have been asked to come up with a redundant WAN link solution for the company I work for.  We are installing a second point-to-point T1 circuit from our office to a data center.  The installation needs to be fault tolerant and also provide load balancing.  I’ve looked into implementing IP CEF, Multilink PPP and also Multichassis Multilink PPP.  Ideally I would like to use 2 routers with a link attached to each one.  The only solution that would work in that scenario would be Multichassis Multilink PPP.  Has anyone ever implemented MMPPP in this type of scenario?  The concept behind MMPPP seems pretty cool but I wonder if it’s a truly an efficient way to load balance.  

I’ve also considered using one router and IP CEF.  Currently the routers on each end of the existing circuit are running RIP2.  Will IP CEF work with RIP?  I was under the impression that you needed to run EIGRP or OSPF for IP CEF to work properly.  Is that correct?

Thanks in advance for any help/suggestions.

IP CEF by itself is much more efficient for load balancing that either MPPP or MMPPP.
You can use it with simple static routes, or EIGRP or OSPF, but I don't think RIP works very well.

My preference would be to run both T1's into the same router.
