[j-nsp] System board memory expansion on M7i

[Hyunseog Ryu]

Basicially routing table size, filtering list, and additional feature such 
as RPF check. 
If you are using this router for Internet core or something like that, I 
would recommend to have maximum memory from start.
Memory cost is not expensive, and routing table size will be grow every 
day. 

If you have to upgrade the memory from production router later, it will be 
the pain in the XXX.

[j-nsp] System board memory expansion on M7i






Hi.

M7i routers can be ordered with 256 or 512 MB RAM system board memory;
any guidelines on what usage scenarios would make 512MB desirable or
even mandatory ?

Our need is a Internet router with 3 full-routing transit feeds and a
bunch of peering connections that made us specify more memory for the
routing engine, but that may or may not impact forwarding engine
requirements. AS and J-Flow are already included in the RFP.
