[c-nsp] Cisco MMPPP

[Edi Guntoro]

Thanks Ben, 
I understand now. Coz previously, regarding the user I though this is a single user with PC/notebook/windows dialing using two different wireless service... is it possible?
regards

i'm talking strictly between your LNS and your CPE here, if you find your MMPPP is giving poor performance due to physical differences between the 2 sessions (ie speed and latency), then try doing something a little more creative like multihopping both ppp sessions onto the one router and using (as you mentioned) cef per-destination load sharing over the 2 unique ppp sessions, or alternatively let a routing protocol handle the work and advertise part of your subnet out one link and part out the other with redundancy, or even GRE tunnels etc etc.. there are quite a few ways you can achieve the desired outcome, this is of course only if your mmppp fails.

Cheers

Thanks Ben,
however what do you mean by "better off load balancing with a routing protocol and/or cef" ? is it disabling the load balancing? as I know this feature enable by default on routing protocol as long as they are equal admin distances.
And is it for traffic out to the internet or traffic coming to the customer ?

the LAC is pretty irrelevant, you need to configure MMPPP capabilities  
on your LNS's, which means an sgbp group on your LNS's for the  
multichassis and "ppp multilink" under your virtual template for the  
MPPP side of things.

I noticed your topology is using 2 seperate wireless services to  
provide the bundle, one word of warning is if the bundles are out of  
sync (speed and latency wise) you will see very poor performance and  
you are better off load balancing with a routing protocol and/or cef.
