[c-nsp] Cisco MMPPP

[Ben Steele]

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

Ben
