[j-nsp] FE Memory Upgrade

128M DRAM on teh CFEB is more than adequate for todays routing needs.  The 
CFEB does hold the 'digested' version of the routing table (it's the CFEBs 
job to distribute routing information to the rest of the system, the RE 
produces the table for the CFEB).

To give you an idea, I'm peered with an M10 (not i) holding up something 
close to a dozen sessions without any pressure on the older 64MB CFEB.  Our 
M7i currently has five peers feeding it and it's only at about 30% util.

The SSRAM mentioned by another poster is for packet forwarding, the DRAM is 
used to store the tables.

I don't think you'll be able to run into any problems with the amount of 
DRAM in the M7i (non-i's with the 64MB FE might though).

YMMV of course.
